Answer: f(-1) = 0
Step-by-step explanation:
Given information
f (-1) or x = -1
Given function
f(x) = 3x² + 2x - 1
Substitute values into the expression
f(-1) = 3 (-1)² + 2 (-1) - 1
Simplify the exponents
f(-1) = 3 (1) + 2 (-1) - 1
Simplify by multiplication
f(-1) = 3 - 2 - 1
Simplify by subtraction
f(-1) = 1 - 1
f(-1) = [tex]\boxed{0}[/tex]
