Advanced Math practice question

Answer: 7

3⁻² = 1/9 and 3⁴ = 81, so the integers from −2 to 4 inclusive work: −2, −1, 0, 1, 2, 3, 4, which is 7 values.

Common wrong answers

If you answered 4

4 counts only the positive exponents 1 to 4.

If you answered 5

5 counts 0 to 4, missing the negative exponents.

If you answered 6

6 misses x = 0 or one endpoint.
