Please help me with writing inequalities for intervals and graphing them.
Ex:
[ 4,5]
( ∞, 1] or (3,∞)
Can someone teach me how on these two problems. Thanks in advance.

Best ResponseYou've already chosen the best response.1to "graph" it, show a number line, and draw a line to show the numbers from 4 to +5 can you do that ?

Best ResponseYou've already chosen the best response.1the [ in [4,5] means 4 is part of the answer to show that, put a solid dot at 4 ditto for the +5

Best ResponseYou've already chosen the best response.1for inequalities people use "x" for the number you want x "between" 4 and 5 you want x bigger than (or equal) to 4 and you want x less than or equal to +5

Best ResponseYou've already chosen the best response.0so im going to use the less than or equal to sign when I write the inequality sign correct?

Best ResponseYou've already chosen the best response.0for the next question does the ∞ in the problem mean that is goes on. meaning that it has no ending?

Best ResponseYou've already chosen the best response.1you put the small point end of < or \(\le\) next to the smaller side, and the big fat side next to the bigger number

Best ResponseYou've already chosen the best response.1infinity is not a number, it is more like an idea: "keep going" I assume you left out an minus sign and mean (  ∞, 1] or (3,∞)

Best ResponseYou've already chosen the best response.1( infinity, 1] to graph, put a solid dot at 1 (solid because of the ] ) and draw a solid line in the direction of more negative numbers. put an arrow on it to show it "keeps going"

Best ResponseYou've already chosen the best response.1on the same graph put (3,∞) the ( 3 means it starts at 3 and ∞) means all numbers after 3 the ( part means 3 is not part of the graph, i.e. all numbers bigger than 3 but not including 3. Use an OPEN circle at 3 instead of a solid dot.
