simply plug in each x-value and see if the y-value matches the one in the pair.
if the equation above is 3.4 to the power of x, then there is none of these are on the graph of f(x)
but if the equation that you are trying to convey is f(x) = 3 * (4^x), then the answer is "a", since f(1) = 3* (4^1) which is the same as 3* 4, which equals 12.
