Quartic functions come in the form of 􀝂 (􀝔) = 􀜽􀝔4 + 􀜾􀝔3 + 􀜿􀝔2 + 􀝀􀝔 + 􀝁 , where 􀜽, 􀜾 . 􀜿, 􀝀 & 􀝁 are all real numbers and where 􀜽 ≠ 0.  \nSimilar to sketching quadratic graphs, cubic graphs can also be represented on a  \nplot. There are two main basic shapes for cubic graphs if 􀜽 > 0: 􀜽 \u003C 0:  \nExample 1: Sketch the curve with the equation 􀝕 = 􀝔 3 + 􀝔 2 − 2􀝔 .  \nBefore we start sketching, we need to know  \n• the general shape of the cubic equation  \n• the location of the roots of the equation  \nWe can compare the function to a general function of 􀝂(􀝔) = 􀜽􀝔3 + 􀜾􀝔2 + 􀜿􀝔 +  \n􀝀 to determine the shape of the curve.  \n􀜽 = 1 and 1 > 0 hence the shape of the graph would look like  .  \nThe next step would be to find the roots of the functions so we can determine where it would cross the 􀝔 axis. To do this we need to solve the quadratic equation of  \n􀝔 3 + 􀝔 2 − 2􀝔 = 0  \n􀝔 (􀝔2 + 􀝔 − 2) = 􀝔 (􀝔 + 2)(􀝔 − 1) = 0  \n􀝔 = 0 􀜽􀝊􀝀 􀝔 − 1 = 0 􀜽􀝊􀝀 􀝔 + 2 = 0 Hence the roots of the function are at:  \n􀝔 = 0 􀜽􀝊􀝀 􀝔 = 1 􀜽􀝊􀝀 􀝔 = −2  \nAt coordinates (0,0), (1,0) & (−2,0) are where the x intercepts will be located.  \nThe same method can be applied to sketching graphs of quartic functions. The basic shapes of these graphs come in the form of:  \n.  \nReciprocal graphs  \nReciprocal graphs that come in the form of 􀝂(􀝔) = 􀯔􀯫 or 􀝂(􀝔) = 􀯔􀯫2, where 􀜽 is any real number, can also be sketched by considering their asymptotes. The graphs of 􀝕 = 􀯔􀯫 and 􀝕 = 􀯔􀯫2 both have asymptotes at 􀝔 = 0 and 􀝕 = 0. The basic shapes of these reciprocal graphs can be illustrated as:  \n􀝕 = 􀜽 􀝓ℎ􀝁􀝎􀝁 􀜽 > 0 􀝔 ,  \n| 􀝕 = − 􀜽\u003Cbr>~~ ~~ 􀝓ℎ􀝁􀝎􀝁 􀜽 \u003C 0 􀝔 ,\u003Cbr>| 􀝕 =  􀜽  􀝓ℎ􀝁􀝎􀝁 􀜽 > 0 􀝔 2 ,\u003Cbr>|\n| --- | --- |\n\n􀝕  􀜽   \n= − 􀝔 2 , 􀝓ℎ􀝁􀝎􀝁 􀜽 \u003C 0  \nPoints of Intersection  \nMultiple functions can be sketched on a single graph to show the points of intersection, which represent the solutions to respective equations.  \nExample 2: Sketch the following functions and find the 􀝔 coordinate of the intersection points.  \n􀝂 (􀝔) = 3􀝔 − 􀝔 2 􀝃 (􀝔) = 2􀝔3 − 􀝔 2  \nThe curves have been sketched using the methods you have learnt in this course. To find the intersection point, we must obtain the 􀝔 coordinate of the locations. To solve this, we need to find the solutions to  \n• 􀝂 (􀝔) = 􀝃 (􀝔)  \n3􀝔 − 􀝔 2 = 2􀝔3 − 􀝔 2  \n2􀝔3 − 3􀝔 = 0  \n􀝔 (2􀝔2 − 3) = 0  \n􀝔 = 0 & 2􀝔2 − 3 = 0    \n􀝔 = 0, 􀝔 = √ ~~ ~~32 & 􀝔 = −√ ~~ ~~32  \nTranslating graphs  \nAdding or subtracting a constant outside, 􀝕 = 􀝂 (􀝔) + 􀜽, or inside, 􀝕 = 􀝂 (􀝔 + 􀜽), a function can translate a graph vertically or horizontally respectively. Note that when translating functions, the asymptote of that function is also translated if it has one.  \n• The translation of 􀝕 = 􀝂 (􀝔) + 􀜽 can be represented by the vector (0􀜽)−􀜽  \n• The translation of 􀝕 = 􀝂 (􀝔 + 􀜽) can be represented by the vector ( 0 ) Example 3: Given that 􀝂(􀝔) = 􀝔 2 , sketch the curve of 􀝕 = 􀝂 (􀝔 − 3) .  \nThis is the graph of 􀝕 = 􀝔 2  \nApplying the translation of 􀝕 = 􀝂 (􀝔 − 3) would shift the graph by three units to the right, forming anew graph of 􀝕 = (􀝔 − 3)2  \nPure Year 1  \nStretching Graphs  \nSimilar to translating graphs, multiplying a constant outside, 􀝕 = 􀜽􀝂 (􀝔), or inside, 􀝕 =􀝂 (􀜽􀝔), a function stretches the graph in the vertical direction or horizontal direction respectively.  \n• 􀝕 = 􀜽􀝂(􀝔) would stretch the graph in the vertical direction by a multiple of 􀜽 .  \n• 􀝕 = 􀝂 (􀜽􀝔) would stretch the graph in the horizontal direction by a multiple of 1  \n􀯔 .  \n• 􀝕 = −􀝂(􀝔) would be the reflection of 􀝕 = 􀝂 (􀝔) in the 􀝔-axis.  \n• 􀝕 = 􀝂 (−􀝔) would be the reflection of 􀝕 = 􀝂 (􀝔) in the 􀝕-axis.  \nExample 4: Given that 􀝂(􀝔) = 16 − 4􀝔2, sketch the curve with the equation 􀝕 = 12 􀝂 (􀝔) .  \n1  \nBefore we start to sketch 􀝕 = 􀝂 (􀝔), we need to know the 􀝔 and 􀝕 intercepts of the  \n2  \ncurve 􀝕 = 􀝂 (􀝔) and how the curve looks like.  \n􀝕 = 16 − 4􀝔2  \n􀝕 = (4 − 2􀝔)(4 + 2􀝔)  \nTo find the 􀝔 intercept we need to equate 􀝕 as 0.  \n0 ","cbCaia4IBg6fSZ7v","https://ap.wps.com/l/cbCaia4IBg6fSZ7v","pdf",616219,"English","# Cubic & Quartic Graphs\n## Sketching Cubic Functions\n## Root-Finding and Intercepts\n## Sketching Quartic and Reciprocal Graphs\n## Points of Intersection\n## Translating Graphs\n## Stretching and Reflection\n## Transforming Graphs with Key Points","[{\"question\":\"How do you determine the general shape of a cubic graph from its equation?\",\"answer\":\"Compare the cubic function to a general form and use the parameter conditions to infer the graph’s overall shape.
