Use the functions a(x) = 3x + 10 and b(x) = 2x − 8 to complete the function operations listed below. Part A: Find (a + b)(x). Show your work. (3 points) Part B: Find (a ⋅ b)(x). Show your work. (3 points) Part C: Find a[b(x)]. Show your work. (4 point

Respuesta :

a(x) = 3x + 10
b(x) = 2x − 8

(a+b)(x)=(3x+10)+(2x-8)=5x+2

(a*b)(x)=(3x+10)(2x-8)=
6x^2-24x+20x-80=
6x^2-4x-80

a[b(x)]=3*b(x)+10=
=3*(2x-8)+10
=6x-24+10
=6x-14
