Answer:
f(- 2) = - 7
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x), that is
f(- 2) = 5(- 2) + 3 = - 10 + 3 = - 7
In this question, you're solving the equation by plugging -2 into x.
Plug -2 into x:
f(x) = 5(-2) + 3
Solve:
f(x) = 5(-2) + 3
f(x) = -10 + 3
f(x) = -7
Answer:
f(x) = -7
