ollie: i need help with my maths homework.

kiera: do i look like a tutor to you?

ollie: no you look beautiful to me, but i still need help and you're blitzing the subject please.

kiera: fine then, what do you want?

ollie: i have to graph y=x^2-25 and i have no idea how.

kiera: well the x-intercepts at at positive 5 and negative 5. and the y-intercept is negative 25, then the turning point would be (0,-25).

ollie: so it's a parabola?

kiera: yes, a parabola, a line that is symmetrical.

ollie: and this one makes connection with the x axis twice yes?

kiera: well there are two intercepts aren't there?

ollie: okay x axis, our formula shall now be y=x^2-25, we will meet twice.

kiera: what?

ollie: your line theory, i figured out a way we can meet multiple times.

kiera: round of applause for you oliver.

ollie: really?

kiera: no.
