Answer:
An exponential parent function is of the form f(x) = a^x, where "a" is a constant and "x" is the variable. It represents exponential growth or decay.
Let's analyze each option to determine which one represents an exponential parent function:
A. f(x) = x²
This function is not an exponential parent function because it has a quadratic term, x², instead of an exponential term.
B. f(x) = 1x1
This function is not an exponential parent function because it is simply the product of two variables, not an exponential function.
C. f(x) = 2*
This function is not an exponential parent function because it is missing the exponent term. The symbol "*" doesn't represent a valid exponent.
D. f(x) = x
This function is not an exponential parent function because it is a linear function, not an exponential function.
Therefore, none of the options provided represent an exponential parent function.
The correct answer is option O A: None.
