Question 1: Given f(x) = 3x + 2, evaluate f(4).

Answer: 14

Question 2: If f(x) = x² - 5, find f(-3).

Answer: 4

Question 3: Calculate f(0) for f(x) = 2x - 7.

Answer: -7

Question 4: Evaluate f(10) where f(x) = 4x + 1.

Answer: 41

Question 5: Given f(x) = x/2 - 3, find f(8).

Answer: 1

Question 6: If f(x) = -2x + 5, compute f(2).

Answer: 1

Question 7: Evaluate f(-4) where f(x) = 5x - 9.

Answer: -29

Question 8: Calculate f(7) for f(x) = x² + 2x.

Answer: 49

Question 9: Evaluate the function f(x) = 3x - 4 at x = -2.

Answer: -10

Question 10: Plot the graph of y = 2x on the grid provided. (Draw the line corresponding to the function.)

Answer: Student draws the line y=2x

Question 11: Construct a triangle on the grid with vertices at (0,0), (3,6), and (0,6).

Answer: Triangle constructed with specified vertices

Question 12: A function is given as f(x) = x² - 4x + 3. Evaluate f(5) and explain the steps.

Answer: f(5)=25-20+3=8; Explanation: Substitute x=5 into the function and simplify.

Question 13: Identify and correct the mistake in evaluating f(x)=3x+2 at f(3): student writes 3*3=9, then adds 2 to get 11. Is this correct? Fix the error.

Answer: The mistake is in the calculation; 3*3=9, then 9+2=11 is correct, so no correction needed. If the student added incorrectly, explain and fix accordingly.
