Question

When we are graphing inequality there is an open and closed circle can please elaborate because i always miss them up

Answer 1

When graphing a function we must know which sing we are using on the inequalities

`<,\leq,>,\ge`

according to the symbol we are using, it will define if the circle is closed or open.

for symbols

`\ge;\leq`

we use closed circles.

and for symbols

`<;>`

we use open circles.

Example

`y=0;x\ge2`

now if the equations were like this

`y=0;x>2`

graph should look like this
