Question

describe the transformation of f(x) that produce g(x)
1. f(x)=4x;G9x)=x/2-1
2.f(x)=5x;g(x)=-2(5x-1)
please help!

Answer 1

***1. f(x)=4x;G(x)=x/2-1

Answer 2

for the first function, you are shifting it down (with the -1), but also scaling it (in this case, stretching it) because of x/2

can you determine what is happening to the second ?
