According to the question, the given points for the expression of the quadratic function are as: (2, 1) (-1, -2).(3,-10)
The standard form of the quadratic equation is: f(x) = [tex]ax^{2} +bx+c=0[/tex]
Using coordinate points the quadratic equation can be written as:
[tex]ax^{2} +bx+c=0[/tex] ⇒[tex]4a+2b+c=0[/tex]; [tex]a-b+c=0[/tex]; [tex]9a+3b+c=0[/tex]
Solving above three equation by the method called substitution and calculated the values of the variable. The calculated values are zero.
Therefore, the formed quadratic function is not quadratic function.
What is quadratic function?
The quadratic function is the polynomial expression and the formed curve is parabola on the graph. The direction of the parabola is either downward or upward or in the direction of left or right. It represent the equation steepness.
