You should know the graphs of \(x\), \(x^2\), \(x^3\), \(\frac{1}{x}\), \(\frac{1}{x^2}\), \(|x|\), \(\sqrt{x}\), \(\ln x\), \(e^x\), \(\sin x\), \(\cos x\), \(\tan x\). You should be able to figure out what the graphs of $\sec x$, $\csc x$, and $\cot x$ look like.

Please see my Teaching Resources for helpful mathematics resources. In particular, if you are reviewing pre-calculus material like fractions, algebra, exponentials and logarithms, and trigonometry, you might find some helpful videos and resources in the precalculus section.
