Our goal is to solve for x
We will first add 7 to both sides
9x = 27
We will then divide both sides by 9
x = 3
Take the value of x-4, and make it positive, then subtract three. The graph would look like the following.
Answer:
B
Step-by-step explanation:
x² - 4x - 7 = 0
(x - 2)² = 11

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² + 2x - 3
f(3) is x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(3) = 3(3)² + 2(3) - 3
- Exponents: f(3) = 3(9) + 2(3) - 3
- Multiply: f(3) = 27 + 6 - 3
- Add: f(3) = 33 - 3
- Subtract: f(3) = 30
