Answer:
B
Step-by-step explanation:
The exponential function is the function of the form
[tex]y=a\cdot b^x,[/tex]
where [tex]b[/tex] is the base and [tex]a[/tex] is the initial value.
The function [tex]y=x^2[/tex] is the quadratic function, which cannot be represented as [tex]y=a\cdot b^x.[/tex] Thus, this function is not exponential.
