Question

If the function h(x) Is defined as vertical stretch by a factor of 2 followed by a reflection in the X-axis of the function F(x) then h(x)=
A)2f(-x)

B) 1/2 f(x)

C) -1/2 f(x)

D) -2f(x)

Answer 1

Answer: C) -1/2 f(x)

Step-by-step explanation:

vertical stretch by a factor of 2 means that the stretch occured at Y - axis.

Then h(x) will transform to 2h(x)

It followed by a reflection in the X-axis of the function F(x) 

Then 2h(x) will transform to - 2h(x)

Where F(x) = - 2h(x)

Make h(x) the subject of the formula

h(x) = - 1/2f(x)

C is the correct answer
