Given the following graph of y=f(x):

a) At what x value(s) is the function discontinuous?b) At what x value(s) is the function not differentiable?c) List all the critical points.d) At what interval(s) is the graph increasing?e) What is the absolute maximum value?f) What is the absolute minimum value?

4. If y’ = (2x — 3)(x + lX4x +7), find the intervals for which y. is Increasing.

r1, Given f(x) — — 8x3 + 18x2 — 15

a) find each of the following:

i) all critical points off;ii) the interval(s) where f is increasing;iii) the interval(s) where f is decreasing;iv) all local maximum and local minimum values.

b) Using the information obtained in a), sketch the graph of f(x) (labelcompletely).

?. Given the function f (x) 2x - X, fmd the equations of the horizontalx2-3x-4

and vertical asymptotes.

Sketch the curve by discussing the relation under the headings

a> domain

b) intcrceprs

c) asymptotesmaximum andjor minimum points.
