Choose the equation that represents an exponential function that passes through the point (2, 36).
Alla [95]
Since we were given only one point, we have to test each exponential function for the point (2,36).

Since exponential functions are of the form y=n(a)^{kx}, The correct option is between option A and option C.

For option A,

f(x)=4(3)^{x}

On substitution, we have;

36=4(3)^{2}

\Rightarrow 36=4\times 9

\Rightarrow 36=36.

Since the point satisfied the exponential function f(x)=4(3)^{x}, the exponential function goes through it.

Hence the correct answer is option A.

No need to test for option C again.
