Sketch the graphs of the curves y = 1 x2, y = cos x,and y = f(x), where f is a function
Chapter 1, Problem 64(choose chapter or problem)
Sketch the graphs of the curves \(y=1-x^{2}\), \(y=\cos x\), and \(y = f(x)\), where \(f\) is a function that satisfies the inequalities
\(1-x^{2} \leq f(x) \leq \cos x\)
for all x in the interval \((-\pi / 2, \pi / 2)\). What can you say about the limit of \(f(x) \text { as } x \rightarrow 0\)? Explain.
Equation Transcription:
y = 1 − x2
y = cos x
y = f(x)
f
1 - x2 f(x) cos x
(−/2, /2)
f(x) as x→0
Text Transcription:
y = 1 − x^2
y = cos x
y = f(x)
f
1 - x^2 leq f(x) leq cos x
(−pi/2, pi/2)
f(x) as x right arrow 0
