A coefficient is the number attached to a variable (k). In front of k is an implied 1 because k*1=k. So the coefficient of the third terms is 1
I believe it's 12=0

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -x² + 10x - 6
f(-5) is x = -5
<u>Step 2: Evaluate</u>
- Substitute: f(-5) = -(-5)² + 10(-5) - 6
- Exponents: f(-5) = -(25) + 10(-5) - 6
- Multiply: f(-5) = -25 - 50 - 6
- Subtract: f(-5) = -75 - 6
- Subtract: f(-5) = -81
Answer:
Step-by-step explanation:
f(x) = x^2 - 2x + 6
to find f(-1), we sub in -1 for every x
f(-1) = (-1^2) - 2(-1) + 6
f(-1) = 1 + 2 + 6
f(-1) = 9 <=======
