  1. 0, 2, -2 Correct answer.
  2. 0, 4
  3. 0, 2
  4. 2, -2

Explanation

Set f(x)=0: x³ - 4x = x(x² - 4) = x(x-2)(x+2) = 0. So x = 0, 2, -2.

Question 45Quantitative Reasoning

A student scored 85, 90, 78, and 92 on four tests. What score must the student earn on the fifth test to have an average of 88?

  1. 88
  2. 90
  3. 95 Correct answer.
  4. 85

Explanation

The sum of the first four scores is 85+90+78+92 = 345. To have an average of 88 over five tests, the total must be 5×88 = 440. So the fifth score must be 440 - 345 = 95.

Question 46Quantitative Reasoning

A cone and a cylinder have the same radius and height. If the volume of the cylinder is 60 cubic cm, what is the volume of the cone?

  1. 60 cubic cm
  2. 20 cubic cm Correct answer.
  3. 30 cubic cm
  4. 180 cubic cm

Explanation

The volume of a cone is one-third the volume of a cylinder with the same base and height. So the cone's volume is 60/3 = 20 cubic cm.

Question 47Quantitative Reasoning

The graph of y = x² - 4x + 3 is a parabola. What are the coordinates of its vertex?

  1. (2, -1) Correct answer.
  2. (-2, 15)
  3. (2, 1)
  4. (4, 3)

Explanation

The x-coordinate of the vertex is -b/(2a) = 4/(2) = 2. Then y = 2² - 4(2) + 3 = 4 - 8 + 3 = -1. So the vertex is (2, -1).

Question 48Quantitative Reasoning

A bag contains 4 red balls and 6 blue balls. Two balls are drawn without replacement. What is the probability that both are red?

  1. 1/5
  2. 8/45
  3. 4/25
  4. 2/15 Correct answer.

Explanation

The probability the first is red is 4/10 = 2/5. Given that, the probability the second is red is 3/9 = 1/3. Multiply: (2/5)×(1/3) = 2/15.

Question 49Quantitative Reasoning

The function f(x) = 3x - 5 is applied to a number, and then the inverse function f⁻¹ is applied to the result. If the final output is 7, what was the original input?

  1. 2
  2. 26
  3. 7 Correct answer.
  4. 16

Explanation

Applying a function and then its inverse returns the original input. So the original input must be the final output, 7. Alternatively, f⁻¹(7) = (7+5)/3 = 4, but that is the intermediate result after f, not the original input. Wait, careful: The problem says f is applied to a number, then f⁻¹ is applied to the result, and the final output is 7. That means f⁻¹(f(x)) = 7, so x = 7. The explanation should state that composition of a function and its inverse yields the identity.

Question 50Quantitative Reasoning

A data set consists of the numbers 2, 4, 4, 4, 5, 5, 7, 9. What is the standard deviation of the data set? (Round to the nearest tenth.)

  1. 2.2
  2. 4.0
  3. 2.0 Correct answer.
  4. 4.5

Explanation

First find the mean: (2+4+4+4+5+5+7+9)/8 = 40/8 = 5. Then compute the squared deviations: (2-5)²=9, (4-5)²=1 (three times), (5-5)²=0 (twice), (7-5)²=4, (9-5)²=16. Sum = 9+3+0+4+16 = 32. Variance = 32/8 = 4. Standard deviation = √4 = 2.0.
