Answer 1

The correct option isC(x) -8x² + 3x - 5

Explanation:

Quadratic function is a function that can be written as in the form of f(x) = ax² + bx + c, where a ≠ 0.

In a quadratic function, the greatest power of the variable is 2.

So, there is only one function from provided options which has greatest power is 2.

Hence, the correct option is C(x) -8x² + 3x - 5

Answer 2

To be a quadratic equation, the first number has to be rasied by the power of 2.

The answer would be c(x) = -8x^2 + 3x-5
