Answer:
D: [0,8]
R: [0,3]
Step-by-step explanation:
The domain is the x-values covered by the graph, while the range is the y-values. So to find each, find the lowest and highest x and y value; since this graph is continuous the domain and range will include all values between these points. In this case, the lowest x is 0 and the highest is 8; the lowest y is 0 and the highest is 3. Then to write the answer write is from least to greatest, finally, surround the point by a parenthesis or bracket. The difference is that parenthesis means the value is not included while a bracket means it is. On this graph all points are included, therefore brackets should be used.
That's an expression, so the only thing you can do is simplify it, but that already looks simplified.
Domain is the x intercepts and range is the y intercepts.
So for this one, all of the ones in the x column would be the domain values.
C. (1,2,3,4) would be your answer.
good luck on the rest of your test!
