Make a table of values. Then, plot and connect the obtained points.
Graph:
Domain: All real numbers. Range: y ≥ 0
Practice makes perfect
To graph the desired function, we will make a table of values. To do so, we will assign some values to the x-variable and calculate the corresponding values for y. For simplicity, we will use even numbers so that the values of y are integers. Make sure to include positive and negative numbers, as well as zero.
We see above that the x-variable can take any value. We also see that y takes values that are greater than or equal to 0. With this in mind, we can write the domain and range of the function.
Domain:& all real numbers
Range:& y≥ 0
