Find the values of x for which the denominator is equal to zero for y=3x+6/x^2-5x+6

Answer:

x = 2

and

x = 3

Step-by-step explanation:

The function given is:

y=\frac{3x+6}{x^2-5x+6}

In this fraction, the bottom part is the denominator. We need to set it equal to 0 and solve for 2 values of x.

x^2-5x+6=0\\x^2-3x-2x+6=0\\x(x-3)-2(x-3)=0\\(x-2)(x-3)=0\\x=2,3

This is middle term factorization process. Hence the 2 solutions (roots) of the denominator is:

x = 2, 3

If the leading coefficient of a quadratic function is negative then the graph of the function extends from?
coldgirl [10]
I wouldn't use the phrase "extends from."  If the leading coeff. is neg, then the graph opens downward.  Without more info we do not know the max of this fn.  If we did know it, we could state that the graph max is (value) and that the graph "extends downward from this value."
