Question

How do I solve for f of f

Answer 1

Answer:

$\large\boxed{(F\circ F)(n)=4n+6}$

Step-by-step explanation:

$F(n)=2n+2\\\\(F\circ F)(n)\to\text{Replace n with 2n + 2 in F(n)}:\\\\(F\circ F)(n)=2(2n+2)+2\qquad\text{use the distributive property}\\\\(F\circ F)(n)=(2)(2n)+(2)(2)+2=4n+4+2=4n+6$
