Question

Given f(x) = - 2x + 5 and g(n) = 3n - 2, evaluate one of the functions with the indicated value f(-3) and explain your answer

[A] f(-3) = -1
[B] g(-3) = - 11
[C] f(-3) = 11
[D] g(-3) =7

Answer 1

[C] f(-3) = 11

Explanation:

• f(x) = - 2x + 5
• f(-3) = - 2(-3) + 5
• f(-3) = -(-6) + 5
• f(-3) = 6 + 5 =11
