Answer-
the standard form of the function is,

<u>Solution-</u>
The standard form of the function is,

Taking the points as (0, 45), (2, 55), (4, 61)
Then putting (0, 45) in the equation,

Then putting (2, 55) with the value of c in the equation,

-------1
Then putting (4, 61) with the value of c in the equation,

------ 2
Solving equation 1 and 2, we get,

Putting the values of a, b, c in the standard form,
