1)Given f(x) = x 5 + 8x 3 + x + 1 has an inverse, find f -1 (1) and f -1 (11). 2)Explain, in words and a picture, why this is true: if f(x) is increasing for all x, then f has an inverse. 3)Why does y = x 2 not really have an inverse?

Unit Circle1) Draw a large circle, centered at the origin.2) Label the coordinates of the circle at the axes.3) Draw in radii at every 45° measure then label all

the radians for these degrees.4) Draw in radii at every 30° measure then label all

the radians for these degrees.5) Draw on your paper an equilateral and isosceles

right triangles.6) See if you can remember the rules on these

special triangles.
