Can anyone help me with this?
Where do the following equations meet. (solve graphically and mathematically)
Y=2x²-6
Y=x-3
$\displaystyle
y=2x^2-6
$
$\displaystyle
y=x-3
$
$\displaystyle
2x^2-6=x-3
$
$\displaystyle
2x^2-x-3=0
$
$\displaystyle
(2x-3)(x+1)=0
$
$\displaystyle x=-1 or x=1.5$
so they meet at -1 and 1.5. you can see this on a graph when the two graphs cross each other
