Question 1

If f(x) = 3x² − 2x + 1, what is f(−1)?

Accepted Answer

f(−1) = 3(1) − 2(−1) + 1 = 3 + 2 + 1 = 6.

Question 2

What is the median of {7, 2, 9, 4, 6}?

Accepted Answer

6

Answer

Ordered set: {2,4,6,7,9}; the middle (3rd) value is 6.

Question 3

Solve the inequality: 3x − 5 > 10

Accepted Answer

x > 5

Answer

Add 5 to both sides: 3x > 15, then divide by 3: x > 5.

Question 4

Two angles are supplementary. One measures 47°. What is the other?

Accepted Answer

133°

Answer

Supplementary angles sum to 180°: 180 − 47 = 133°.
