1. For the function y=f(x) shown graphed below, answer the following questions.
(a) Find the value of f(2) + f(-1).
(b) State all intervals over which f(x) <0.
y = f (x)

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
