The value of h(3) is 120 ⇒ B
Step-by-step explanation:
To find the value of f(x) at x = a, do that
- Substitute x by a
- Find the value of f(a)
∵
- To find h(3) substitute x by 3
∴
∵ = 81
∵ (3)² = 9
- Substitute them in the function above
∴ h(3) = 2(81) - 4(9) - 2(3)
∴ h(3) = 162 - 36 - 6
∴ h(3) = 120
The value of h(3) is 120
