Answer:
option (4)
Step-by-step explanation:
The general form of a quadratic function is given by :
Where a,b and c are real numbers and a is nonzero.
Option (1)
It is a quadratic function. Here, a = 3, b = 12 and c = 5
Option (2),
It is a quadratic function where a = 1, b = 1 and c =1
Option (3),
It can also be written as :
It is a quadratic function where a = 5, b = 8 and c = 0
Option (4),
It can also be written as :
f(x) = 5x + 3
It is a linear function. It is not a quadratic function.
Hence, option (4) is the correct option. It is not a quadratic function.
