false
The graph of a polynomial in X crosses the X-axis at x-intercepts known as the roots of the polynomial, the values of x that solve the equation.(polynomial in X) = 0 or otherwise y=0
2 or 5
set the values of the y equal to zero
Yes.
A local minimum.
Substitute that value of the variable and evaluate the polynomial.
false
Find values of the variable for which the value of the polynomial is zero.
it means to see which number is bigger and which number is smaller

It is halfway along the distribution of set values. There are as many members of the set with values smaller than the median as there are with values bigger than it.
2 or 5
zero
4 and 5 -4 and -8
-2 and -6
