Explain why the focus of a parabola is never on the parabola itself

Mrrafil [7]

This is because the focus of the parabola is the point which the parabola wraps itself around, for lack of a better word.

The only point we need to be really concerned about that is on the parabola is the vertex, right at the center.

I hope my answer has come to your help. God bless and have a nice day ahead!

3x + y = 4 x - 2y = 3

Anna007 [38]

Eliminate y's
multily top equation by 2 and add to 2nd

6x+2y=8
1x-2y=3 +
7x+0y=11

7x=11
x=11/7
sub back

x-2y=3
11/7-2y=3
add 2y both sides
11/7=2y+3
minus 3 which is 21/7
-10/7=2y
divide by 2 or times 1/2
-5/7=y

(x,y)
$( \frac{11}{7}, \frac{-5}{7})$
