What is the degree of a polynomial function?

In Mathematics and Geometry, the degree of a polynomial function is sometimes referred to as an absolute degree and it's the greatest exponent (leading coefficient) of each of its term.

Based on the information provided, we have the following polynomial function:

h(x) = x³ + 2x² – 11x – 12

Since the leading coefficient of the above polynomial function is positive, and the degree is odd, the end behavior can be described as follows;

As x tends towards negative infinity, h(x) tends towards negative infinity i.e x → -∞, h(x) → -∞.

As x tends towards positive infinity, h(x) tends towards positive infinity i.e x → ∞, h(x) → ∞.

The squareroot of a negative number is notdefined in the realm of real numbers.

We have,

The squareroot of a negative number is not defined in the realm of real numbers.

The square root function is only defined for non-negative real numbers.

In this case, the expression "negative 9 squared" means the square of negative 9, which is positive 81.

However, taking the square root of the negative of positive 81 would involve imaginary numbers.

If we consider the square root of -81 in the realm of complex numbers, it can be represented as ±9i, where i is the imaginary unit (√-1).

Thus,

The squareroot of a negative number is not defined in the realm of real numbers.

Since the negative 9 is squared, you would get 81. So you would have the square root of a negative 81. Therefore you would have the square root of negative one (i) times the square root of 81 (9). So, the answer is 9i.
