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
