If g(x)=x+1/x-2 and h(x) = 4 – x, what is the value of (gxh) (-3)

For this case we have the following functions:

We must find (g * h) (x)

By definition we have to:

So:

Now, we evaluate the function at x = -3:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
