, Understanding of this topic will vary based on your current
math level. To recreate the image below, you can use the simplify command
and the ) tab to simplify the difference quotient for f(x) = x

− 16.
4.5 Solve using a defined function
When we solve f(x) = 0 for f(x) = x
2
−16 we get two solutions x = −4 and
x = 4.
