Use the graph of y = f(x) to complete the following. 

(a) Identify the x- and y-intercepts. 

(b) Find the slope of the graph. 

(c) Give any zeros of f. 

(d) Identify the interval(s) where f is positive or negative. 

(e) Identify the interval(s) where f is increasing or decreasing. Is f ever increasing and negative on the same interval? Is f ever decreasing and positive on the same interval? 

(f) Find the slope-intercept form for y = f(x). Can you tell from the slope-intercept form if f is increasing or decreasing? Explain.
