Question

1. f(x) = 2x + 6 Evaluate f(2)

2. f(x) = 3x Evaluate f(a + 1)


3. f(x) = 3x – 1 and g(x) = 5x + 3 Evaluate f(2) + g(3)

Answer 1

Answer:8x

Explanation:

Answer 2

1) f(x)=2x+6
f(2)=2(2)+6
=4+6
=10

2)f(x)=3x
f(a+1)=3(a+1)
=3a+3
3)f(x)=3x-1 and g(x)=5x+3

f(2)=3(2)-1
f(2)=6-1
=5
g(3)=5x+3
=5(3)+32
=15+3
=18


f(2)+f(3)=5+18
=23.
