,

Step 1

Insert the values of and into the equation to find if the ordered pair is a solution.

Step 2

Subtract from .

Step 3

The inequality is never true.

No solution

Step 4

Step 4.1

The leading term in a polynomial is the term with the highest degree.

Step 4.2

The leading coefficient in a polynomial is the coefficient of the leading term.

Step 5

Since there are no real x-intercepts and the leading coefficient is negative, the parabola opens down and is always less than .

No solution

Step 6

Since the equation is not true when the values are used, the ordered pair is not a solution.

The ordered pair is not a solution to the equation.
