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)

The function () after the vertical stretched by a factor of two and followed by a reflection in the X- axis will be,

Now the reflection arise along the X- axis. Thus the above function will reflect and the value of it will become,

Rewrite the equation,

Hence the function () after the vertical stretched by a factor of two and followed by a reflection in the X- axis will be,

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

i believe the answer is the polygon, heptagon.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
