Question

If f(x)=3x^2-2x+1 find f(-2)

Answer 1

17

Explanation:

3(-2)^2 - 2(-2) + 1

12 - 2(-2) + 1

12 + 5

17

Answer 2

f(-2) = 3(-2)² - 2(-2) + 1 = 17

Explanation:

f(x) = 3x² - 2x + 1

f(-2) = 3(-2)² - 2(-2) + 1

= 3 × 4 + 4 + 1

= 12 + 5

f(-2) = 17

Thus, f(-2) = 3(-2)² - 2(-2) + 1 = 17
