Nction.
f(x) = -x² + 3x + 11
Find f(-1)

Answer 1

f(-1) = -(-1)^2 + 3(-1) + 11
f(-1) = 2 + -3 + 11
f(-1) = 10

Answer 2

f(-1) = 7

Explanation:

Hello!

You can evaluate for f(-1) by substituting -1 for x in the equation.

Evaluate f(-1)

• f(x) = -x² + 3x + 11
• f(-1) = -(-1)² + 3(-1) + 11
• f(-1) = -1 -3 + 11
• f(-1) = -4 + 11
• f(-1) = 7

f(-1) is 7.
