Dude... your eggnog is still full-blown.   Crosses the Y-axis HOW MANY times????
Oops, meant to say x-axis...it was my dxsleyia kicking in!

Yes, I can see that...

However, it does not depend upon crossing the x-axis.  Given the "proper" values, it could cross the x-axis a number of times and never reach .2 within the range.  But it does, so 4 IS the correct answer.

I should have been more clear in my response: The line crosses the x-axis 4 times and clearly has values that exceed .2 so it stands to reason that it must pass through .2 4 times.

Sure. I thought it meant a straight line...as in a line segment, which is what we programmers are used to defining as a line. Going back and reading it, I'll say E is the answer because the shape of the curve is not parabolic.

If the function were a line, the slopes of the segments (0,-9),(1, -4) and (1, -4), (3,0) would be the same.  However, the slope of  (0,-9),(1, -4) is 5, and the slope of (1, -4), (3,0) is 2.  The graph of f cannot be a line.  

However, if the function (undefined in the problem) was, say, y=(x-3)^2, ((x-3) squared), the graph would contain the points (0,-9),(1, -4), (3,0), a parabola symmetric to y=3.  
Max value of f is at (3,0) and y<=0 for all points x, y in f.
