The required graph is as follows:
All the tools & learning materials you need for study success - in one app.
Get started for freeDetermine whether\({\bf{f}}\)is even, odd, or neither. If you have a graphing calculator, use it to check your answer visually.
64.\({\bf{f}}\left( {\bf{x}} \right){\bf{ = 1 + 3}}{{\bf{x}}^{\bf{3}}}{\bf{ - }}{{\bf{x}}^{\bf{5}}}\)
For the function \(f\) whose graph is shown, arrange the following numbers in increasing order:
\(0\) \(1\) \({f^'}\left( 2 \right)\) \({f^'}\left( 3 \right)\) \({f^'}\left( 5 \right)\) \({f^{''}}\left( 5 \right)\)
Some scientists believe that the average surface temperature of the world has been rising steadily. They have modeled the temperature by the linear function\({\bf{T = 0}}{\bf{.02t + 8}}{\bf{.5}}\), where\({\bf{T}}\)is the temperature in\({}^{\bf{o}}{\bf{C}}\)and\({\bf{t}}\)represents years since 1900.
(a) What do the slope and\({\bf{T}}\)-intercept represent?
(b) Use the equation to predict the average global surface temperature in 2100.
Express the surface area of a cube as a function of its volume.
Find
(a) \({\bf{f + g}}\)
(b) \({\bf{f}} - {\bf{g}}\)
(c) \({\bf{fg}}\)
(d) \({\bf{f}}/{\bf{g}}\)
and state their domains.
38. \({\bf{f}}\left( x \right) = \sqrt {3 - x} \) \(g\left( x \right) = \sqrt {{x^2} - 1} \)
