Answer 1

Answer 2

f[g(x)] = 7x + 15
f[g(x)] = 7x + 27
f[g(x)] = 7x2 + 15
f[g(x)] = 7x2 + 27

Answer 3

f(x) = 7x+13

f(x) = 7( x )+13

f(g(x)) = 7( g(x) )+13 ... replace every x with g(x)

f(g(x)) = 7( x+2 )+13 ... replace every g(x) on the right side with x+2

Answer 4

I'll let you simplify

Answer 5

ok hold on

Answer 6

7x+27?
