which ordered pairs lie on the graph of the exponential equation f(x)=3(1/4)^x?
select each correct answer.
a. (−2,48)
b. (0,3)
c. (2,3/16)
d (12,0)

For each of the given answer choices, substitute the x-value into the given equation f(x) = 3(1/4)^x and see the equation gives the same f(x), or y-value.

Remember f(x) is the same thing as y and so coordinates for a point are in problem is (x, f(x))

Let's try the first coordinate (-2, 48). The x-value given by the coordinate is -2 and the f(x) value is 48.
Substituting x as -2 into the equation,

This matches with the answer choice (-2, 48) so A should be correct.
But you can also check the other answer using the same process to make sure.
