Determine if the function is one-to-one. (5 points)

Find the inverse of the function. f(x) = x3 + 8 (5 points)

Rewrite with only sin x and cos x. sin 3x – cos x (6 points)

Determine algebraically whether the function is even, odd, or neither even nor odd. (5 points)

Find the period of the function. y = -3 cos x (5 points)

Choose the graph which matches the function. (5 points) f(x) = 2x+2

Find the exact value of sin-1(-0.5). (5 points)

Verify the identity. cos (x – y) – cos (x + y) = 2 sin x sin y (5 points)

Match the phase of a turn with the definition of or movements that take place in that phase.   Initiation – beginning or approximately the top third of a turn Control – middle part of a turn, in which the skis are guided into and out of the fall line, and where most steering occurs, and the skier accelerates Finish – last third of a turn; beginning shortly after the fall line and continuing until direction change is accomplished. The last moments of the finish lead straight into the next turn’s initiation phase (so they overlap slightly)
