Question

Describe the transformation that occurs when:

g(x) = f(x) becomes g(x) = 8(f(x))

The graph will stretch vertically and horizontally

The graph will stretch vertically making it look thinner

The graph will not change

The graph will shrink vertically making it look fatter

Answer 1

The graph is being stretched vertically, so it will be thinner.

Explanation:

g(x) = 8f(x) means that you are multiplying each original y-value by 8, so the graph gets thinner. When there's a number n greater than 1 in front of the function, it's a vertical stretch by n.
