1-41.

Given

*f*(*x*)*= x*^{2}+ 2*x*and*g*(*x*) =, find the following: Homework Help ✎ *g*(*x*− 2)*f*(*g*(8))*g*(*f*(8))*f*(*f*(1))*f*(*x*+ 1)*g*(*f*(*x*))

Replace every *x* in the *g* function with the expression (*x* − 2). Then simplify.

Find *g*(8) first. Then replace every *x* in the *f* function with the value of *g*(8). Simplify.

Find *f*(8) first. Then replace every *x* in the *g* function with the value of *f*(8). Simplify.

Find *f*(1) first. Then replace every *x* in the *f* function with the value of *f*(1). Simplify.
