Let f(x)= 4x +8 and g(x)= x2 + 3, find
the following:
1-5. (f◦g)(x) ?
6-10. (g◦f)(x) ?
yung 1-5 and 6-10 po yung question pa sagot po ng maayos advance thank you

Answer:
1. ( f o g) (x)
g(x)=x^2+3
f o g = 4x + 8 if g(x^2 + 3)
= 4(x^2 + 3) + 8
= 4x^2 + 12 + 8
= 4x^2 + 20
2. (g o f) (x)
f(x)= 4x + 8
g o f = x^2 + 3
= (4x + 8)^2 + 3
= 16x^2 + 32x + 32x + 64 + 3
= 16x^2 + 64x + 67
