Question

Given the following function: f(x) = 3 – 5x
Evaluate f(-8) + f(-10) = ?

Answer 1

• Answer:

f(-8) + f(-10) = 96

• Explanation:

f(-8) = 3 - 5×(-8)

= 3 + 40

= 43

f(-10) = 3 - 5×(-10)

= 3 + 50

= 53

f(-8) + f(-10) = 43 + 53 = 96

Answer 2

96

Explanation:

f(x) = 3 – 5x

• f(-8) + f(-10) =
• 3 - 5*(-8) + 3 - 5*(-10) =
• 3 + 40 + 3 + 50 =
• 96

f(-8) + f(-10) = 96
