Explanation:
Consider the provided statement:
We need to find the exponential function that passes through the point (2,80),
Now consider the provided option:
The equation
and
are not exponential function. Thus, these two options are wrong.
It is given that the exponential function passes through the point (2,80),
Substitute x = 2 in
.
Therefore, this function doesn't passes through the point (2,80).
Substitute x = 2 in
.
![f(2)=80](https://img.qammunity.org/2020/formulas/mathematics/middle-school/s47l7bsdjhy3dck3g0cihkos3ygvwwcjp4.png)
Hence, the correct option is D).
