Question

Which equation represents an exponential function that passes through the point (2,80)?
Fx) = 4(x)5
F(x)=5(x)4
F(x)= 4(5)x
F(x)=5(4)x

Answer 1

Answer:

$f(x) = 5 \times 4^{x}$

Step-by-step explanation:

There are four examples of the equation.  

Now, the general form of an exponential function is $f(x) = a^{x}$, where a > 0 and a ≠ 1.

Now, if the given functions passes through the point ( 2, 80 ), then $f(x) = 5 \times 4^{x}$ will be the required equation as it satisfies the point ( 2, 80 ).
