Explanation:

domain : the interval or set of all valid x-values.

range : the interval or set of all valid y-values (function result values).

A is correct

theoretically all real numbers are valid as x. but for this application of the function only non-negative integer values make sense (e.g. half a cycle does not make any sense).

C is correct

via A we are allowing all real numbers to be valid input values, so, we have to allow also all real numbers to be valid output (function result) values.

D is correct

the y-intercept means the y-value, when the function curve intersects the y-axis.

this is only possible, when x = 0.

5⁰ = 1

as any x⁰ = 1

F is correct

the bigger x, the bigger 5^x.

and the smaller x, the closer y, the function result, gets to 0. particularly, when we allow negative input values (as we said in A).
