Help me with my homework

Er, I meant that x at the interval (0,1) and (1,3) and (3,4), not x at the coordinates 0,1 etc. Usually we write that x is an element of (0,1), meaning x on the interval between 0 and 1, exclusive. x being an element of [0,1] means that x is on the interval 0 and 1, inclusive. Another way of writing x as an element of [0,1] is 0 < x < 1 and x as an element of (0,1) is 0 < x < 1. If you look on your graph during these intervals, you’ll see that the slope is slanted upwards.

edit: Are you sure number 6 is phrased like that? It doesn’t really make any sense right now…

It was cut off.

Add continuous to it.

Oh. Then I guess it’s continuous everywhere except 0 and 1 then. I don’t really understand why you had to graph it; just set the denominator to zero.

Okay, I did the calculus test yesterday.

The first question was just finding limits with squareroots as denominators; with Lim x-> a number besides infinity. I had trouble. A lot of trouble. I know you have to multiply by the conjugate, but then I got lost.

Pretty much the rest was finding sums of geometric sequences and stuffs.
