If yes, is the function even or odd? Find the center and radius of the circle 2 x 2 + 2 y 2 − 12 x + 4 y + 14 = 0 . I Given: f ( x ) = 4 x 2 − 3 x + 2 f (a + h) − f (a) Find: h II Find an equation of the line passing through the point (−3,5) and perpendicular to 2 x − 7 y = 8 . Give the final answer in standard form. III An airplane flew a distance of 1000 mi in 8/5 hours moving with the wind and it flew the same distance in 2 hours moving against the wind. What was the speed of the airplane? IV Determine whether the function f ( x ) = 2 x 2 − 6 x + 4 has the minimum or maximum value and find it. Find the domain, all asymptotes, and holes, if any. x3 + x 2 − 2 x R( x) = 2 x + 2x − 3 Determine the interval on which the graph lies above the x-axis. V VI Given: f ( x ) = 1 + 3 x − 4 . Find f −1 ( x ) if it exists. VII Use the Intermediate Value Theorem to show that the polynomial f ( x ) = −2 x 5 − 3 x 4 + 4 x 2 + x + 1 has a zero in the interval [1, 2] . VIII Describe the transformations that need to be performed on the graph of f ( x ) in order to obtain the graph of g ( x). Find the domain, range, asymptote, and intercepts of the function g ( x ) . (a) f ( x ) = 2 x and (b) f ( x ) = log 2 x and g ( x ) = 2log 2 ( − x − 4 ) − 2 g ( x ) = −23− x + 1 IX X Write as a single logarithm: ⎛m⎞ log 3 ⎜ ⎟ + 2log 3 ( mn ) − 3log 3 m ⎝n⎠ Solve the equation: log ( x + 1) + log ( x − 2 ) = 1 Solve the equation: 2 x+1 = 51− x XI XII ...
