1. ## Integer help!

Thank you taking the time.

I need to write the expression in words that described the interval of numbers below.

(4,21/2)

3. Given that A = {x|x > 3} and B = {x|-3< x < 2}, express the following in interval notation. (The < has a line under it so it means equal to. I can't make it equal to.)

A U B interval ____________

A n B interval ____________

i can try this 3 u mentioned
A = {3,4,5,6....} - u mentioned > 3
B = {-3,-2,-1,1,2.3}
A u B ={-3,-2,-1,0,1,2,3,,4,5,6....}
A n B ={3}
