Sketch the graph of the first function by plotting points if necessary. Then use transformation(s) to obtain the graph of the second function. \(y=\tan x, \quad y=\tan \left(x+\frac{\pi}{3}\right)\)
Plot the graph of the function \(f\) in (a) the standard viewing window and (b) the indicated window. $$ f(x)=x^{3}-20 x^{2}+8 x-10 ; \quad[-20,20] \times[-1200,100] $$
Find the zero(s) of the function f to five decimal places. $$ f(x)=x^{4}-2 x^{3}+3 x-1 $$
Determine whether \(h=g \circ f\) is even, odd, or neither, given that a. both \(g\) and \(f\) are even. b. \(g\) is even and \(f\) is odd. c. \(g\) is odd and \(f\) is even. d. both \(g\) and \(f\) are odd.
Find the inverse of \(f .\) Then sketch the graphs of \(f\) and \(f^{-1}\) on the
same set of axes.
$$
f(x)=\cot ^{-1}\left(\frac{x}{3}\right), \quad 0
