Answer:
f(- 2) = 2
Step-by-step explanation:
To evaluate f(- 2), substitute x = - 2 into f(x)
f(- 2) = 3(- 2)² + 5(- 2) = (3 × 4) - 10 = 12 - 10 = 2
Answer:
[tex]2[/tex]
Step-by-step explanation:
[tex]f(x) = 3x^2 + 5x[/tex]
[tex]f(-2) = 3(-2)^2 + 5(-2)[/tex]
[tex]f(-2) = 3(4) + 5(-2)[/tex]
[tex]f(-2) = 12 + -10[/tex]
[tex]f(-2) = 2[/tex]
