Question

For the given functions f(x), write a function g(x) for the transformations: f(x)=x; down 1 unit; stretch by 3

Answer 1

is that a horizontal stretch or vertical stretch?

Answer 2

umm, i was kinda wondering that too, but that is all it says.....

Answer 3

if it's a vertical stretch, then \(\Large y=3f(x)-1 \)
if it's a horizontal stretch, then \(\Large y = f(\frac{1}{3}x)-1 \)

simplify this in either case....
