Functions....help please. Not too hard.
if g(x) = 3x+1

Answer 1

if g(x) = 3x+1 and h(x) = 5 + x^2, evaluate

g(2n + 3 ) + 7h (-4 )

Answer 2

replace every x in g(x) with 2n+3
replace every x in h(x) with -4
3(2n+3)+1 + 7h(5+(-4^2))
6n+9+1 + 35h+112h
6n+10+147h

Answer 3

Not the right answer, but thanks for trying =)
