Which equation represents an exponential function that passes through the point (2.80)?
A f(x) = 4(x)^5
B f(x) = 5(x)^4
C f(x) = 4(5)^x
D f(x) = 5(4)^x

B f(x) = 5(x)^4

D f(x) = 5(4)^x

Step-by-step explanation:

We want to find the exponential function that represents a function passing through (2,80).

All we need to do is quickly substitute the point into the functions and select the function it satisfies.

For A f(x) = 4(x)^5, we have

For B f(x) = 5(x)^4, we have

For C f(x) = 4(5)^x, we have:

For D f(x) = 5(4)^x, we have;

Options B and D are correct
