Saladin:
Good job man, this way, we can understand what they want!
pjb13:
1) Given h(x) = (x+1)(x-3). How do I know that h is differentiable on (-1,3) ?
2)How close to 2 must x be for the values of g(x) = x^2 to be within 0.2 from 4?
I know how to solve most of this...I reach an answer of -0.051<x-2<0.049
Then it says to insure both ends of the last compound inequality are satisfied take -0.049<x-2<0.049
My question is why cant we take -0.051<x-2<0.051....how do I know which one to take?
Thanx
