Which of the following is a quadratic function?


f(x)=3x-1

f(x)=5x3-x+1

f(x)=x-2-3x+1

f(x)=2

f(x)=5x2-3x+1


Yanıt Açıklaması:

A quadratic function is a polynomial function of degree2. Thus the largest exponent must be 2, and all the exponents must be natural numbers. Only the function in E satisfies these conditions.
