For the function illustrated above, what is the domain? A{1, 2, 3, 4, 9, 12} B{1, 4, 9, 12} C{2, 3, 4} D{4, 9}

The correct option is C

C)  (2,3,4)

Step-by-step explanation:

Domain can be defined as the set of all possible values of input, for which we can calculate the values of output. The values of input are independent, while the values of output are dependent on the values of input.

In the diagram, we can see that the arrow represents that for a certain number in A, we get a number from B. Which means that A represents the input while B represents the output.

As A is the input, all values of A form the domain of the function, which means that domain in {2,3,4}

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
