1Find the remainder when the polynomial f(x) = x^3 - 3x^2 + 5x - 7 is divided by (x - 2).

A.-1

B.-7

C.1

D.9

Explanation: According to the Remainder Theorem, when a polynomial f(x) is divided by (x - c), the remainder is f(c). Substituting x = 2 into the function gives f(2) = 2^3 - 3(2)^2 + 5(2) - 7 = 8 - 12 + 10 - 7 = -1.

2If (x - 3) is a factor of the polynomial g(x) = x^3 - kx^2 + 4x - 12, find the value of the constant k.

A.1

B.2

C.3

D.4

Explanation: By the Factor Theorem, if (x - 3) is a factor of g(x), then g(3) = 0. Substituting x = 3 gives 3^3 - k(3)^2 + 4(3) - 12 = 0, which simplifies to 27 - 9k + 12 - 12 = 0. Solving 27 - 9k = 0 yields k = 3.

3The polynomial f(x) = x^3 + ax^2 + bx - 6 has a factor of (x - 1) and leaves a remainder of -10 when divided by (x + 1). Find the values of the constants a and b.

A.a = 1, b = 4

B.a = 2, b = 3

C.a = -1, b = 6

D.a = 3, b = 2

Explanation: Since (x - 1) is a factor, f(1) = 1 + a + b - 6 = 0, which gives a + b = 5. Since division by (x + 1) leaves a remainder of -10, f(-1) = -1 + a - b - 6 = -10, which gives a - b = -3. Adding the two equations gives 2a = 2, so a = 1, and substituting back gives b = 4.

4Express the quadratic expression 2x^2 - 12x + 11 in completed square form, a(x - h)^2 + k.

A.2(x - 3)^2 - 7

B.2(x - 3)^2 + 11

C.2(x - 6)^2 - 25

D.2(x - 3)^2 - 18

Explanation: Factor out the coefficient of x^2 from the first two terms: 2(x^2 - 6x) + 11. Complete the square inside the bracket: 2[(x - 3)^2 - 9] + 11. Distribute the 2 to obtain 2(x - 3)^2 - 18 + 11 = 2(x - 3)^2 - 7.

5State the maximum value of the function f(x) = 5 - 4x - x^2 and the value of x at which it occurs.

A.Maximum value of 9 at x = -2

B.Maximum value of 5 at x = 0

C.Maximum value of 9 at x = 2

D.Minimum value of -9 at x = -2

Explanation: Completing the square for f(x) yields f(x) = -(x^2 + 4x - 5) = -[(x + 2)^2 - 9] = 9 - (x + 2)^2. Because the squared term is subtracted, the maximum value is 9, which occurs when the squared term is zero, i.e., x + 2 = 0, so x = -2.

6Find the range of values of x for which x^2 - 5x - 6 > 0.

A.-1 < x < 6

B.x < -1 or x > 6

C.x < 1 or x > -6

D.x <= -1 or x >= 6

Explanation: Factoring the quadratic inequality gives (x - 6)(x + 1) > 0. The critical values are x = -1 and x = 6. For the product to be positive, x must lie outside the interval between the roots, which means x < -1 or x > 6.

7Find the range of values of k for which the quadratic equation 3x^2 + kx + 12 = 0 has real and distinct roots.

A.-12 < k < 12

B.k < -12 or k > 12

C.k > 12

D.k < 12

Explanation: For the quadratic equation to have real and distinct roots, its discriminant must be strictly positive: b^2 - 4ac > 0. Here, a = 3, b = k, and c = 12, so k^2 - 4(3)(12) > 0, which simplifies to k^2 - 144 > 0. Solving this quadratic inequality yields k < -12 or k > 12.

8Solve the equation 2^(2x+1) - 9(2^x) + 4 = 0 for real values of x.

A.x = -1, 2

B.x = 1, -2

C.x = 0, 2

D.x = -1, 4

Explanation: Rewrite the equation as 2 * (2^x)^2 - 9(2^x) + 4 = 0. Let y = 2^x, giving the quadratic equation 2y^2 - 9y + 4 = 0. Factoring gives (2y - 1)(y - 4) = 0, so y = 1/2 or y = 4. Substituting back, 2^x = 1/2 yields x = -1, and 2^x = 4 yields x = 2.

9Solve the equation log_3(x) + log_3(x - 2) = 1.

A.x = 3 and x = -1

B.x = 3 only

C.x = -1 only

D.x = 9 and x = 1

Explanation: Applying log laws, log_3(x(x - 2)) = 1, which implies x^2 - 2x = 3^1, or x^2 - 2x - 3 = 0. Factoring gives (x - 3)(x + 1) = 0, so x = 3 or x = -1. Because log_3(x) is only defined for x > 0 and log_3(x - 2) is only defined for x > 2, x = -1 is extraneous, leaving x = 3 as the only valid solution.

10Evaluate the expression log_2(16 * sqrt(2)) - log_2(0.25).

A.2.5

B.6.5

C.5.5

D.4.5

Explanation: Express each argument as a power of 2. First, 16 * sqrt(2) = 2^4 * 2^(1/2) = 2^(4.5), so log_2(16 * sqrt(2)) = 4.5. Second, 0.25 = 1/4 = 2^(-2), so log_2(0.25) = -2. The expression becomes 4.5 - (-2) = 6.5.
