The domain and range is the set of xx and yy values of a function
Notice that the curve starts at the x-axis at x=-3x=−3, curves down to y=-3y=−3 and goes back to the x-axis at x=3x=3
This means that the curve will cover all real values of xx greater than or equal to -3−3 and less than or equal to 33 and all real values of yy greater than or equal to -3−3 and less than or equal to 00
The domain and range is the set of xx and yy values of a function
Notice that the line starts at the point (-1,1)(−1,1) and ends at point `(1,3)“
This means that the line will cover all real values of xx greater than or equal to -1−1 and less than or equal to 11 and all real values of yy greater than or equal to 11 and less than or equal to 33
