Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -2x² + 3x - 6
f(3) is x = 3 for the function f(x)
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function]: f(3) = -2(3)² + 3(3) - 6
- Exponents: f(3) = -2(9) + 3(3) - 6
- Multiply: f(3) = -18 + 9 - 6
- Add: f(3) = -9 - 6
- Subtract: f(3) = -15
Answer: Im pretty sure it is the equal sign with the line between it
pretty sure that is it tho
Hope that helped
Step-by-step explanation:
Answer:
(2, 1).
Step-by-step explanation:
x^2 - 4x + 5 = 0
(x - 2)^2 - 4 + 5 = 0
(x - 2)^2 + 1 = 0
The vertex is at (2, 1).
