Question

Determine the constants a and b, given that the parabola
y = ax^2+bx+3 passes through (−2, 34)and (3,9).
a=?
b=?

Answer 1

Substitute the known values and solve the resulting system.

Answer 2

Help me somepne please!!!

Answer 3

Insert eh values of x and y given into the equation one-by-one.

You willl then get 2 equations. Solve both of them simultaneously.

Answer 4

Like this:
y = ax^2+bx+3 passes through (−2, 34)and (3,9).

34 = a(-2)^2 + b(-2) + 3 and 9 = a(3)^2 + b(3) + 3

Simplify both.
