Which expression is equivalent to (x² - 9) / (x - 3)?
Answer: x + 3
x² - 9 factors as (x+3)(x-3), so dividing by (x-3) leaves x+3.
What is the slope of the line passing through (2, 5) and (6, 13)?
Answer: 2
Slope = (13-5)/(6-2) = 8/4 = 2.
Solve for x: 2x² - 8 = 0
Answer: x = ±2
2x² = 8 → x² = 4 → x = ±2.
Which of the following is the correct domain of f(x) = 1/(x² - 4)?
Answer: All real x except x = ±2
The denominator x² - 4 = 0 when x = ±2, so those values are excluded.
What is the value of log₂(32)?
Answer: 5
2⁵ = 32, so log₂(32) = 5.
If f(x) = 3x - 4, what is f⁻¹(x)?
Answer: (x + 4)/3
Swap x and y in y = 3x - 4 and solve: x = 3y - 4 → y = (x+4)/3.
Which inequality represents the solution to -3x + 6 > 0?
Answer: x < 2
-3x > -6 → dividing by -3 and flipping: x < 2.
