In an exponential function, where does the variable sit?
AIn the base part
BIn the numerator
CIn the coefficient
DIn the exponent
Answer & Solution
Correct answer: D. In the exponent
1. An exponential function is written as a fixed base raised to a variable power.
2. So the variable sits in the exponent rather than in the base.
3. That is the reverse of a power such as x squared, where the variable is the base.
