f(x) = (cos 2x − cos x)/(x2)
by graphing and zooming in toward the point where the graph crosses the y-axis, estimate the value of lim x → 0 f(x). Check the value of the limit by evaluating f(x) for values of x that approach 0. (Round your answers to six decimal places.)
A) f(.1) B) f(.01) C) f(.001) D) f(.0001)
From the graphs it appears that the y-intercept is at -1.5.
