Given the function a(x)=4x−8 with range r: {0,4,8}, which of the following represents the domain, d of function a? select one: a. d: {0, 1, 2} b. d: {2, 2, 6} c. d: {-2, -1, 0} d. d: {2, 3, 4}

Option D.

Step-by-step explanation:

The given function is

We need to find the domain of the function for range R:{0,4,8}.

Domain is the set of input values and range is the set of output values.

Substitute a(x)=0 in the given function.

Substitute a(x)=4 in the given function.

Substitute a(x)=8 in the given function.

The input values of function for outputs 0, 4 and 8 are 2, 3 and 4 respectively.

Domain = {2,3,4}

Therefore, the correct option is D.
