Which equation represents an exponential function that passes through the point (2, 80)?
Of(x) = 4(x)5
O f(x) = 5(x)4
O f(x) = 4(5)*
Of(x) = 5(4)*

Respuesta :

Answer:

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

Step-by-step explanation:

The first two functions are polynomial functions with a constant exponent (4). While the second function would give you the correct output y=80 for x=2, it's still not an exponential function.

only the fourth function satisfies all conditions.
