Write an equation for each representation of a quadratic function given below.

Let, us assume that quadratic equation is :

Now, putting x = 0 and y = -4 :

Also, putting x = 1 and y = -3 :

 ....2)

Also, putting x = 2 and y = 0 :

....3)

Solving equation 2 and 3, we get :

a = 1 and b = 0

Therefore, the quadratic equation is given by .

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
