Which system of linear inequalities has the point (3, –2) in its solution set?
a) y > x and y > x+1,
b) y > 2x and y < -x,
c) y > -x and y < x,
d) y > x/2 and y < -x.
(c) Sketch a graph of a continuous function y = f(1) that satisfies the following: • f(-5) = f(0) = 0; • f'(x) < 0 for -5 < <-3 and 1 < x < 5; • f'(x) > 0 for -3 < x < 1; • f'(x) < 0 for -2 < x < 3; • F"(x) > 0 for -5 < x < -2 and 3 < x < 5; Clearly label and local extrema and points of inflection.
