Which represents a quadratic function?



f(x) = −8x3 − 16x2 − 4x


f (x) = x 2 + 2x − 5


f(x) = + 1


f(x) = 0x2 − 9x + 7

A quadratic function is one of the form f(x) = ax^2 + bx + c, where a, b, and c are numbers with a not equal to zero.
In the given question, the only function that satisfies the condition of a quadratic function is f(x) = x^2 + 2x - 5 and thus is the correct answer to the question.

Answer:

f (x) = 3/4 x ^2 + 2x − 5
