Get started for freeA roast turkey is taken from an oven when its temperature has reached \({\bf{185}}\;^\circ {\bf{F}}\) and is placed on a table in a room where the temperature \({\bf{75}}\;^\circ {\bf{F}}\). The graph shows how the temperature of the turkey decreases and eventually approaches room temperature. By measuring the slope of the tangent, estimate the rate of change of the temperature after an hour.
Each limit represents the derivative of some function f at some number a. State such an f and a in each case.
\(\mathop {{\bf{lim}}}\limits_{h \to {\bf{0}}} \frac{{\sqrt {{\bf{9}} + h} - {\bf{3}}}}{h}\)
19-32: Prove the statement using the \(\varepsilon ,\delta \) definition of a limit.
28. \(\mathop {\lim }\limits_{x \to - {6^ + }} \sqrt(8){{6 + x}} = 0\)
Find an equation of the tangent line to the graph of \(y = B\left( x \right)\)at\(x = 6\),if\(B\left( {\bf{6}} \right) = {\bf{0}}\),and \(B'\left( 6 \right) = - \frac{1}{2}\).
Which of the following functions \(f\) has a removable discontinuity at \(a\)? If the discontinuity is removable, find a function \(g\) that agrees with \(f\) for \(x \ne a\)and is continuous at \(a\).
(a) \(f\left( x \right) = \frac{{{x^4} - 1}}{{x - 1}},a = 1\)
(b) \(f\left( x \right) = \frac{{{x^3} - {x^2} - 2x}}{{x - 2}},a = 2\)
(c)\(f\left( x \right) = \left [{\sin x} \right],a = \pi \)
