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)
1 answer:
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
