Question

Given the function f(x)=√5x, which transformation results in the horizontal stretching and reflecting across the y-axis?
A.)f(x) is replaced with f(6x)
B.)f(x) is replaced with f(-3x)
C.) f(x) is replaced with f(x-7)
D.) f(x) is replaced with f(-2/3x)

Answer 1

The refection in y axis will make the term in x negative so its either B or D.
The stretching will  come from the -2/3 x

Answer is D
