Which of the following is true about the parabola f(x) = x2 + 6x - 9: The y intercept is (0, -18)
The axis of symmetry is x 3
The parabola will open up.
The parabola will open down.

The degree is of degree 5, hence the function is classified as Quintic: Option A is correct.

An equation is categorized as a quadratic, linear, or polynomial equation depending on the degree of the polynomial.

The highest exponential value of the leading term in an expression is the degree of the function.

Given the function -6x^5 +4x^2 +11, we can see that the leading terms have a degree of 5 showing that the function is a polynomial function.

Since the degree is of degree 5, hence the function is classified as Quintic
