If f(x) = 3x - 2, what is f(4)?
Answer and explanation
Correct answer: D. 10
- Step 1: Substitute 4 for x: 3(4) - 2. Step 2. Multiply first, then subtract: 12 - 2 = 10. Answer: 10. Why not the others: the other values come from changing the sign, changing the order of operations or dropping the constant.
