The range of a function is the possible y values of a function that result when we substitute all the possible x-values into the function.
When finding the domain, remember:
• Substitute different x-values into the expression for y to see what is happening.
• Make sure you look for minimum and maximum values of y.
• Draw a sketch!
For example, If f(x) = (x – 3)/(x + 3), the domain to be all Reals except for -3 and the range is all Reals except for 1.
