$$D:-3\le x \le 1; R:-2 \le y \le2$$

anonymous · Answer

Is there an equation to go with the domain and range? Just giving the domain and range can mean anything without the equation of the line.

anonymous · Answer

no theres no specific equation. thats the domain and range and its put onto a graph as the domain and range are shown

anonymous · Answer

You need to look at the graph. Do you know how to do the vertical line test?

anonymous · Answer

no sorry i dont. ive been absent from school for a week and a half so i just got this work and was told to do it with no way of knowing how

anonymous · Answer

Alright. The vertical line test is taking your finger and moving it left to right over the graph. If your finger touches the graph in more than one spot then it is not a function. Otherwise it's a function.
