Answer:

3x^{2}-2x+5

Step-by-step explanation:

The value for each value of x is given by f(x) in the table, the quadratic equation which satisfies all the values f(x)  at each value of x is given by:

3x^{2}-2x+5.

This can be found by substituting all the values of x in the equation and check whether it satisfies the corresponding value f(x) or not.

Therefore, substituting x=-2 in the quadratic equation 3x^{2}-2x+5,

3(-2)^{2}-2(-2)+5

3(4)+4+5

=21

Again, substituting x=-1 in the same equation, we have

3(-1)^{2}-2(-1)+5

3+2+5

=10

Putting x=0,

3(0)^{2}-2(0)+5

=5

Putting x=1,

3(1)^{2}-2(1)+5

=6

Putting x=2,

3(2)^{2}-2(2)+5

=13

Hence, the quadratic equation which is represented by the table is 3x^{2}-2x+5
