Determine whether each statement is true or false If the statement is false, make the necessary change(s) to produce a true statement. Prove that if \(f\) and \(g\) are even functions, then \(f g\) is also an even function.
Determine whether each statement makes sense or does not make sense, and explain your reasoning. My graph is decreasing on \((-\infty, a)\) and increasing on \((a, \infty)\) so \(f(a)\) must be a relative maximum.
Graph \(y_{1}=x^{2}-2 x, y_{2}=x,\) and \(y_{3}=y_{1} \div y_{2}\) in the same [-10,10,1] by [-10,10,1] vicwing rectangle. Then use the TRACE l feature to trace along \(y_{3}\). What happens at \(x=0 ?\) Explain why this occurs.
a. Graph the functions \(f(x)=x^{n}\) for \(n=2,4,\) and 6 in a [-2,2,1] by [-1,3,1] viewing rectangle. b. Graph the functions \(f(x)=x^{n}\) for \(n=1,3,\) and 5 in a [-2,2,1] by [-2,2,1] viewing rectangle. c. If \(n\) is positive and even, where is the graph of \(f(x)=x^{n}\) increasing and where is it decreasing? d. If \(n\) is positive and odd, what can you conclude about the graph of \(f(x)=x^{n}\) in terms of increasing or decreasing behavior? e. Graph all six functions in a [-1,3,1] by [-1,3,1] viewing rectangle. What do you observe about the graphs in terms of how flat or how steep they are?
