Inverse of a function is also a function, if and only if the function is One - to - One. This means no y value occurs in the range of the function more than once.
If we observe the given options, we can see option B, C and D have some repeated values of y. Only the function in option A is one to one. Hence the inverse of function given in option A will also be a function.
So, the answer to this question is option A
Given the function
Consider the point (2, 56) i.e. when x = 2
Therefore, point (2, 56) lie on the graph of the given exponential function.
Consider the point (-2, -4) i.e. when x = -2
Therefore, point (-2, -4) lie on the graph of the given exponential function.
Consider the point (8, 0) i.e. when x = 8
Therefore, point (8, 0) does not lie on the graph of the given exponential function.
Consider the point (24, 1) i.e. when x = 24
Therefore, point (24, 1) does not lie on the graph of the given exponential function.
