Advanced Math practice question

The function f is defined by f(x) = 2ˣ + 3. What is the value of f(5)?

Answer: 35

f(5) = 2⁵ + 3 = 32 + 3 = 35.

Common wrong answers

If you answered 13
13 computes 2 × 5 + 3, treating the exponent as a multiplier.
If you answered 32
32 is 2⁵ alone, without the +3.
If you answered 256
256 computes 2⁸, adding 3 to the exponent instead of to the result.
