Answer:

Equation of parabola is: [tex]y=4x^{2} +3x-6[/tex]

Step-by-step explanation:

By plotting a rough graph with the values given we get an opening upward parabola.

Standard equation for a parabola opening upwards is given by:

[tex]y=ax^{2}+bx+c[/tex]

We can solve for a,b,c by substituting the given values of x and y.

Putting x=0 and y=-6 in the above equation,we get:

c = -6

Putting x=-2 and y=4, we get:

[tex]4a-2b=10[/tex]  ---------1

Putting x=4 and y=70, we get:

[tex]16a+4b=76[/tex] --------2

Solving equation 1 and 2, we get

a=4 and b=3

Hence [tex]y=4x^{2} +3x-6[/tex]
