Question

This is a graph of the polynomial $y=x^n$ , where $n$ is a/an number.

• A. even
• B. odd
• C. negative
• D. irrational

Answer 1

The correct option is A even

When $n$ is odd in $x^n$, the graph lies in the first and third quadrants. When $n$ is even in $x^n$, the graph lies in the first and second quadrants. Here, the graph lies in the first and second quadrants only. Hence, $n$ is even.
