Quadratic function

Write the equation of the quadratic function which includes points A (-1, 10), B (2, 19), C (1,4)

Correct result:

a =  0
b =  0
c =  0


System of equations are non-linear.
The equations have the following integer solutions:

Number of solutions found: 1
a1=6, b1=-3, c1=1

Our linear equations calculator calculates it.
f(x)=ax2=bx+c=6x23x+1f(x)=ax^2 = bx+c = 6x^2-3x+1

We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
