  1. A polynomial p(x) = x³ - 2x² - 5x + 6. Which is a factor of p(x)?

    Answer: (x - 3)

    p(3) = 27 - 18 - 15 + 6 = 0, so by the Factor Theorem, (x-3) is a factor.

  2. What is the average rate of change of f(x) = x² + 3x from x = 1 to x = 4?

    Answer: 8

    f(4) = 16+12 = 28, f(1) = 1+3 = 4; average rate = (28-4)/(4-1) = 24/3 = 8.

  3. In a triangle, angles are in the ratio 2:3:7. What is the measure of the largest angle?

    Answer: 126°

    Sum of ratios = 12 parts; each part = 180/12 = 15°; largest angle = 7 × 15° = 105°.

  4. Which is the simplified form of (2x³y²)³ / (4x²y)?

    Answer: 2x⁷y⁵

    Numerator: 8x⁹y⁶; divide by 4x²y → 2x⁷y⁵.

  5. A set of data has mean 50 and standard deviation 8. A data value of 66 has a z-score of:

    Answer: 2.0

    z = (66 - 50) / 8 = 16/8 = 2.0.

  6. Which equation represents a parabola with vertex at (2, -3) opening upward?

    Answer: y = (x-2)² - 3

    Vertex form is y = a(x-h)² + k with h=2, k=-3 and a>0 for upward opening: y = (x-2)² - 3.

  7. If log₂(x) = 5, what is the value of log₂(x²)?

    Answer: 10

    log₂(x²) = 2·log₂(x) = 2·5 = 10 by the power rule of logarithms.
