Find the critical points. Then find and classify all the extreme values:

(I) f(x) = 2x^2 +5x -1, x E [-2,0]

(II) f(x) = x^2 / (1+x^2), x E [-1,2]

Where E is that sideways looking M, not sigma (unless they mean the same thing?).

(III) f(x) = sin2x - x, 0<=x<=pi

Explain your work. Thanks! :)

The position function is s(t)=t^3 - 3t^2 + 4 for an object moving along a linear path. distance = meters
Answer the following:
(a) On what interval(s) is the object moving to the right? to the left? changing direction?
(b) Determine the position, velocity, and acceleration when t=0 and t=3 seconds and then describe the motion at these points in time.
(c) Determine the distance traveled after the first 5 seconds.
(d) Determine the displacement after the first 5 seconds.

I really don't understand, so could you please explain how to solve the problem as well? Thank-you!

It's a proof:

Let G be a group. Prove that the mapping alpha(g)=g^(-1) for all g in G is an automorphism if and only if G is Abelian.

mike was walking through a railway train tunnel when he suddenly heard a train approaching. looking at the markers inside the tunnel, he saw that he was 2/5 the distance from one end of the tunnel and 3/5 the distance from teh other end of the tunnel.

if mike runs as fast as he can towards either end, he will escape from the tunnel just as the train reaches him.

if the train is moving 60km/h, how fast is mike running?

thanks for the answers!

Suppose that a cyclic group G has exactly three subgroups: G itself, {e}, and a subgroup of order 7. How many elements are in G? What can you say if 7 is replaced with p where p is a prime?

(e is the identity)

Ok, aren't e and G always subgroups of G? Is the answer supposed to be 7? I don't know how to think about this.

the number of centimeters, d, that a spring is compressed from its natural uncompressed position is given by d=sq.rt2w/k,where k is the number of joules of work done to move the spring and k is the spring constant. solve this equation for w. use the result to determine the work needed to move a spring 4 centimeters if it has a spring constant of 0.2
