Assume f(x)=2x+8 and g(×)=5 what is the value of (g o f)(3)
RUDIKE [14]
We first need to find f(3).

f(3) = 2(3) + 8

f(3) = 6 + 8

f(3) = 14

We now want g(f(3)).

We know that f(3) is 14.

We also know that g(x) is 5.

As you know, 5 is a constant. No matter what the value of x is for g(x), it will not change the value of g(x).

So, g(f(3)) = g(14) = 5.

Answer: g(f(3)) = 5.

To get the area of a rectangle, multiply the side lengths.
Our side lengths of this rectangle is 1/2 and 3/4, so let's multiply them.

\dfrac{1}{2} *  \dfrac{3}{4} =  \dfrac{3}{8}

Thus, the area of this rectangle is 3/8 ft². I hope this helps! :)
