Question

which of the following is a polynomail?
a. x^-x+2
b.x^-2-1
c.x^4-2
d.(x^6-4)(x^-5+10

Answer 1

a polynomial is a function where variable(s) is/are raised to the power, and this power is a whole number.

Answer 2

Some examples of a polynomial is: \(\\[1.2em]\)
\(\large\color{black}{ \displaystyle y=0 \\[0.7em] }\)
\(\large\color{black}{ \displaystyle y=-34 \\[0.7em] }\)
\(\large\color{black}{ \displaystyle y=x^2+3 \\[0.7em] }\)
\(\large\color{black}{ \displaystyle y=-x-4 \\[0.7em] }\)
\(\large\color{black}{ \displaystyle y=12x^6-7x^5+2x^4+3x^3-x^2-x+3 \\[0.7em] }\)
