Sample answer: <span>For </span>f<span>(3), the input is 3 and you are looking for the output. To determine the function's value when </span>x<span> = 3, go to the value of 3 on the </span>x<span>-axis and then locate the graph for that value of </span>x<span>. Determine the value of </span>y<span> from the </span>y<span>-axis at that location on the graph.

I'm not at my desk and can't check it out right now.
But I think you should try 10 and -42 .
In mathematics, a polynomial is an algebraic expression containing more than two terms. When the polynomial could not be reduced to a lower degree, it is classified as a prime polynomial. Just like whole numbers, a prime polynomial cannot be broken down into factors except 1 and by the number itself. Take for example, the polynomial x² + 5x + 6. It can be reduces to its factors x=-2 and -3. That would be expressed to x² + 5x + 6 = (x+2)(x+3). But if the polynomial is, say, x² + 5x + 7, there is no roots that are whole numbers. Therefore, it can't be reduced into factored groups because it is a prime polynomial.
8 over 20 equals 6 over 15
