Answer:
3rd degree of polynomial with 4 terms.
Step-by-step explanation:
The given expression is
The given expression is a polynomial.
Let's find the degree of the polynomial.
The degree of the polynomial is highest degrees of the expression.
To find the degree of expression, we need to find highest degrees.
x^2 y = 2 + 1 = 3 (Add the power of the variables)
xyz = 1 + 1 + 1 = 3 (Added the power of the variables)
Therefore, the highest degree of the polynomial is 3.
There are 4 terms.
So, it is 3rd degree of polynomial with 4 terms.

Answer:
<h2> (2, -1)</h2>Step-by-step explanation:
Given the function f(x) = 8x³ − 12x² − 48x, <em>the critical point of the function occurs at its turning point i,e at f'(x) = 0</em>
First we have to differentiate the function as shown;
Hence the critical numbers of the function are (2, -1)
