Question

Which represents a quadratic function?

Answer 1

Answer:

B

Step-by-step explanation:

Okay! So before we do this, first we have to understand the function. The function is,

y = ax^2 + bx + c, where a does not equal to 0.

The answer is not A, since bx is bx^2 which is incorrect.

The answer isn't C, since there isn't an ax^2 or a bc.

The answer isn't D since there a can't be 0.

The only correct answer is B, for it has all the parts.

x^2 + 2x -5.
