Determine the domain and range of the function (equation is below) a. {x| all real numbers}; {y| y > 0} b. {x| all real numbers}; {y| y ≥ 0} c. {x| x > 0}; {y| all real numbers} d. {x| x ≥ 0}; {y| all real numbers}

A. {x| all real numbers}; {y| y > 0}

Step-by-step explanation:

We have been given the function and we are required to find domain and range of this function. In order to find domain and range of this function, let us first rewrite this function as an exponential function and simplify it as much as possible.

This is an exponential function of the form

We know that domain of an exponential function is all real numbers and range is all positive real numbers.

Therefore, correct choice would be option (A).

450 is the final answer! : )

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
