Question

compare the graph of the linear function to the parent graph f(x)=x. f(x)=4x. a) vertical shift of 4 units upb) vertical shifts of 4 units downc) vertical stretch using a scale factor of 4d) vertical shrink using a scale factor of 4

Answer 1

We have to compare the function f(x) = 4x to the parent function p(x) = x.

We have a scale factor k = 4.

As the scale factor has an absolute value greater than 1, this is a vertical stretch using a scale factor of 4.

We can see it in a graph as:

Answer: c) vertical stretch using a scale factor of 4
