Question

Which of the following describes the graph of y = RootIndex 3 StartRoot 8 x minus 64 EndRoot minus 5 compared to the parent cube root function?

Answer 1

Answer:

The first function is shifted down 5 units, strechted by a scale factor of 8, and shifted right side 8 units.

Step-by-step explanation:

The given function is

$y=\sqrt[3]{8x-64}-5$

Where its parent function is $y=\sqrt[3]{x}$

Observe that the binomial inside the cubic root has a GCF,

$y=\sqrt[3]{8(x-8)}-5$

The image attached shows a comparison between these two functions.

Basically, the first function is shifted down 5 units, strechted by a scale factor of 8, and shifted right side 8 units.
