,Section A - Polynomial Functions
Q1.
Determine the exact value of sin(75°)cos(15°) + cos(75°)sin(15°) without using a calculator.
A. 1 B. 3/2
C. 1/2 D. 2/2
Correct: A - 1
Rationale:The expression is the sine addition formula: sin(A+B) = sin(75°+15°) = sin(90°) = 1.
Thus, the sum equals 1, not any other trigonometric value.
Q2.
Solve for x in the interval [0, 2): 2cos²x - 3cosx + 1 = 0.
A. x = 0, /3, 5/3 B. x = 0, 2/3, 4/3
C. x = /3, , 5/3 D. x = 0, /3,
Correct: A - x = 0, /3, 5/3
Rationale:Factor to (2cosx - 1)(cosx - 1) = 0, giving cosx = 1/2 or cosx = 1. Solutions are x =
0, /3, 5/3. The other options include incorrect angles or miss solutions.
Q3.
Given f(x) = (x² - 4)/(x - 2), which statement is true?
A. f has a vertical asymptote at x = 2 B. f has a removable discontinuity at x = 2
C. f is continuous at x = 2 D. f has a horizontal asymptote at y = 1
Correct: B - f has a removable discontinuity at x = 2
Rationale:The numerator factors to (x-2)(x+2), so f(x) = x+2 for x "` 2. The discontinuity at x =
2 is removable because the limit exists. There is no vertical asymptote, and f is not defined at
x = 2, so not continuous. Horizontal asymptote is not relevant for a linear function.
Q4.
Evaluate lim_{x->} (3x² + 2x - 1)/(5x² - 4x + 7).
A. 0 B. 3/5
C. D. 1
Page 3
, Section A - Polynomial Functions
Correct: B - 3/5
Rationale:Divide numerator and denominator by x², the highest power. As x!’", terms with
1/x and 1/x² approach 0, leaving 3/5. The limit is finite and equals the ratio of leading
coefficients.
Q5.
If logx + log(x - 2) = 3, solve for x.
A. x = 4 B. x = -2 or 4
C. x = 2 D. x = 4 or -2
Correct: A - x = 4
Rationale:Combine logs: log ‚[x(x-2)] = 3, so x(x-2) = 8, yielding x² - 2x - 8 = 0, so x = 4 or -2.
Since logarithms require positive arguments, x = -2 is extraneous. Thus x = 4.
Q6.
Convert 135° to radians and find the exact value of tan(135°).
A. 3/4, -1 B. /4, 1
C. 3/4, 1 D. 2/3, -3
Correct: A - 3/4, -1
Rationale:135° = 135 * À/180 = 3À/4. In the second quadrant, tan is negative, and tan(135°) =
-tan(45°) = -1. Option A correctly gives both the radian measure and the tangent value.
Q7.
Determine the equation of the horizontal asymptote for f(x) = (2x³ + 1)/(x³ - 5).
A. y = 0 B. y = 2
C. y = -1/5 D. No horizontal asymptote
Correct: B - y = 2
Rationale:The degrees of numerator and denominator are equal (both 3), so the horizontal
asymptote is the ratio of leading coefficients: 2/1 = 2. Thus y = 2.
Q8.
If f(x) = x³ - 2x² + x - 2, find f(1).
A. 0 B. -2
