Scaling and TranslatingLet's calculate the key points of the following cuberoot function.By setting 3x - 2 equal to -8, -1,0, 1, 8, we find the x-values forthe key points of this function.Calculate the last two x-values yourself.Scaling and TranslatingAfter we have calculated the x-values of the key points, wecan select an appropriate scale and plot the key points.A different x-scale, but still the characteristic cube rootshape.
One More Cube Root ExampleCan you visualize the shape and orientation of this function?You calculate the x-values ofthe other three key points.What horizontal scale should we use to plot thesepoints as simply as possible?One More Cube Root ExampleTo plot these points quickly, the most natural scale to use onthe x-axis would be counting by 1/4.(3/2,-1)(13/4,-2)Now we recognize this pattern even when it is reversed!
