Question

So I got half way through this problem and am stuck I have to solve and put in interval notation I have so far...... Problem : 2x<8 or x+3>=10
I ended up getting x<4 and x>=7..... Is this correct and if so how do I put it in interval notation?

Answer 1

that is correct
for interval notation, remember if is equal to use brackets otherwise use parenthesis
use +-infinity for left and right bounds

-> (-inf, 4) U [7,inf)
