Question

Need help with this question ?!?!?!?

What is the equation in standard form of a parabola that models the values in the table?
x -2 0 4
f(x) 1 5 -59

Answer 1

f(x) = ax^2 + bx + c is the general formula

plug in the above values into this formula
then solve the resulting system of equations

Answer 2

i'll do the first one:
(-2,1):-

1 = (-2)^2a + -2b + c
1 = 4a - 2b + c

Answer 3

you'll have 3 equations to solve for a,b and c

Answer 4

Soo all i have to do is plug in a number for each letter?

Answer 5

plug in a number for x and f(x)

eg the next point (0,5) is x = 0, f(x) = 5

Answer 6

ohhh ok, i get it now :)

Answer 7

good
