Each year, Ng analyzes how the Chinese zodiac will affect everything from the global political climate to what the world's health will look like in the coming months.
The degree of a polynomial function is the highest exponent to which the dependent variable is raised. For example, f(x) = 4x 5 â x 2 + 5 is a fifth-degree polynomial, because its highest exponent is 5.
To determine the degree of a polynomial that is not in standard form (for example ( x + 1 ) 2 â ( x â 1 ) 2 {\displaystyle (x+1)^{2}-(x-1)^{2}} ), one has to put it first in standard form by expanding the products (by distributivity) and combining the like terms; for example ( x + 1 ) 2 â ( x â 1 ) 2 = 4 x {\displaystyle (x+1)^{2}-(x-1)^{2}=4x} is ...
