Question

how would you work out the equation of a parabola's with the points (-2;0) , (5;0) and (3;5) ?

Answer 1

y=ax^2+bx+c is general form, these points lie on the parabola so these will satisfy this equation. put these values and solve for a,b,c

Answer 2

for example (-2,0)
x=-2 , y=0
put in the equation
0=a(-2)^2+(-2)b+c
4a+c=2b
similary do the rest and solve for a,b,c

Answer 3

Alright, I get it . Thanks man.
