SHOW YOUR WORK. f(x) = 5x2 - 4x + 1
g(x) = 3x - 2
h(x) = x + 1
k(x) = 4x
1) f(5) =
2) (g+h)(x) =
3) f(1) - h(1) =

Explanation:

1.
f(5) = 5(5^2) - 4(5) + 1
= 125 - 20 + 1
= 106

2. (g + h)(x) = (3x - 2) + (x + 1)
= 3x - 2 + x + 1
= 4x - 1

3. f(1) - h(1) = [5(1^2) - 4(1) + 1] - [(1) + 1]
= (5 - 4 + 1) - (2)
= 2 - 2
= 0
