Problem 2
- Find the measure of side x.
- Side AB = 5
- Angle A = 42°
- Angle C = 90°
- Use the trigonometric ratios.
- Find side x using the cosine rule
Problem 3
- Domain: All real numbers
- Range: y ≤ 2
Problem 4
- Domain: All real numbers
- Range: y ≤ 4
Problem 5
- Write the equation in vertex form
- y = x² + 2x - 3
Problem 6
- Write the equation in vertex form
- y = x² + 10x + 16
Problem 7
- f(n) = 4n + 2
- Find f(-5)
- Substitute n = -5 into the equation
- f(-5) = 4 * (-5) + 2
- f(-5) = -18
Problem 8
- f(x) = (x + 4)² − 6
- Find f(x) when f(x) = 3
- Substitute f(x) = 3 into the equation
- 3 = (x + 4)² − 6
