Can a quadratic equation considered a quadratic function without a constant term

See below.

Step-by-step explanation:

(a) 1.75 + 1.25 = 3 inches.

Now the other side is 3.25 inches long, so a triangle can't be constructed.

For a triangle to be formed the length of any side must be less than the sum of the other 2 sides.

(b) if the length of the longest side is reduced to  less than 3 , say 2.5 inches then a triangle can be constructed.
