Describe how it was translated from

 $f\left(x\right)=x^2$  to  $f\left(x\right)=x^2-9$  .

A student says that all linear functions are either increasing or decreasing. Do you​ agree? Explain.

• Yes. Linear functions always have an​ x- and​ y-intercept, so they are always increasing or decreasing.

• No. Linear functions can also be​ constant, which means neither increasing nor decreasing.

• No. Linear functions can be both increasing and decreasing.

• Yes. Linear functions always have ​(−∞​,∞​) as their domain and​ range, so they are always increasing or decreasing.
