To solve this, since you know that h(x) is 11 and that it also equals -4x+3, you set them equal to one another which would look like this: 11=-4x+3.
Then, to solve for x, which is what I am assuming the question is asking, you would subtract 3 from both sides to isolate -4x, which would result in this:
-4x=8
Now, to solve for x, divide both sides by -4, and you get your answer which is x=-2

Step-by-step explanation:
<u>Step 1: Define</u>
P(x) = x³ + 4x² - 3x + 1
P(1) is x = 1
P(-2) is x = -2
<u>Step 2: Evaluate</u>
<em>P(1)</em>
- Substitute: P(1) = 1³ + 4(1)² - 3(1) + 1
- Exponents: P(1) = 1 + 4(1) - 3(1) + 1
- Multiply: P(1) = 1 + 4 - 3 + 1
- Add: P(1) = 5 - 3 + 1
- Subtract: P(1) = 2 + 1
- Add: P(1) = 3
<em>P(-2)</em>
- Substitute: P(-2) = (-2)³ + 4(-2)² - 3(-2) + 1
- Exponents: P(-2) = -8 + 4(4) - 3(-2) + 1
- Multiply: P(-2) = -8 + 16 + 6 + 1
- Add: P(-2) = 8 + 6 + 1
- Add: P(-2) = 14 + 1
- Add: P(-2) = 15
Answer:
the slope is positive 2
the slope-intecept form would be, y=2x+3
