(r*s) = (x+1)(3x+4) = 3x² + 3x + 4x + 4 = 3x² + 7x + 4
(r-s)(x) = x+1 - (3x+4) = x + 1 - 3x - 4 = -2x - 3
(r+s)(x) = x + 1 + 3x + 4 = 4x + 5
(r + s)(2) = 4(2) + 5 = 8 + 5 = 13

- Parenthesis
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
<u>Algebra I</u>
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
