Write the inequality in interval notation

Question

x greater than or equals 1

This is [1,infinity) right?

Answer 1

looks good

x> 1

is the same as x is in the interval [1, infinity)

use a bracket to indicate x includes 1

use a parentheses to indicate x does not include infinity, as infinity is not a real number, just a limit that is approached but never reached.

instead of infinity, you might use the symbol that looks like an 8 on its side
