Answer: f(-3) = -4
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given expression
f(n) = 3n + 5
Substitute values into the expression
f(-3) = 3(-3) + 5
Simplify by multiplication
f(-3) = -9 + 5
Simplify by addition
f(-3) = [tex]\boxed{-4}[/tex]
Hope this helps!! :)
