The 1/2 will change all values of f(x) to 1/2 f(x) so the graph of f(x) will shrink vertically by a factor of 1/2.

The third option is the correct one.

f(x) vs (a)(f(x))

if a<0, that is known as a vertical compresion

our 1st 3 option show a vertical compression

since a<0, it will shrink vertically by a factor o 1/2

last option, hmm, range is height or y value

by subtracting 2, you move it in the x direction so no change in range from that

however, vertically compressing it makes the y values smallers so range is different

answer is only the 3rd option, shrink vertically

How do you find the area of this composite figure?

Illusion [34]

If you notice the picture below

the composite figure is just a trapezoid sitting on top of a rectangle
and then, the rectangle has a triangular hole in it

so.. get the area of the trapezoid $\bf \textit{area of a trapezoid}=A=\cfrac{h}{2}(a+b)\qquad 
\begin{cases}
h=height\\
a,b=\textit{parallel sides or bases}
\end{cases}$

then get the area of the rectangle, which is just a 12x14
and then get the area of the triangle, which surely you know is 1/2 bh

then, subtract the triangle's area from the rectangle's area

and whatever is left, namely the difference, add that to the area of the trapezoid, and that's the composite's area

namely the area of the trapezoid plus the rectangle's, minus the triangle's
