Me!
which of the following functions is quadratic?
a. f(x) = 2x^2 + 3x -5
b. f(x) = 3 ( 3 - x )
c. f(x) = 7^2
d. f(x) = 2/x^2

A. f(x) = 2x^2 + 3x -5

Step-by-step explanation:

A quadratic function is a function of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero.Therefore; The function, f(x) = 2x^2 + 3x -5, is a quadratic function since it is in the form of  f(x) = ax² + bx + c.Additionally, a quadratic equation is an equation of second degree, such that it contains at least one term that is squared. In this case, 2x^2.
