What is the domain?

• $\left(-\infty,\infty\right)$

• (-2,3)

• $\left(-\infty,3\right]$

Choose everything that is true about the function.

• it has a local maximum

• it has a local minimum

• it bounded above and below

• $\lim_{x\rightarrow\infty}f\left(x\right)=\infty$

• it is strictly increasing on its domain

When asked to evaluate a limit, what is the value of your answer?

• x-intercept(s)-where graph crosses the x-axis

• DNE (does not exist)

• y-value- what f(x) approaches as x approaches a specific number

• $\pm\infty$
