Given three points of a quadratic function, find the equation that defines the function: (-2, 20)(0, -2)(1, -4)
Stels [109]

Answer:

y=3x^2-5x-2

Step-by-step explanation:

Let the quadratic function be

y=ax^2+bx+c

The given points must satisfy this function;

Substitute (-2,20).

20=4a-2b+c..(1)

Substitute (0,-2)

c=-2...(2)

Substitute (1,-4);

-4=a+b+c...(3)

Put equation (2) into equation (1)

20=4a-2b+-2

4a-2b=22

2a-b=11...(4)

Put equation (2) into equation (3)

-4=a+b-2...(3)

a+b=-2...(5)

Add equation (4) and (5)

3a=9

Divide both sides by 3

a=3

Put a=3 in  equation 5.

3+b=-2

b=-2-3

b=-5

The quadratic function is;

y=3x^2-5x-2
