What are the coordinates of the hole in the graph of the function f(x) ? f(x)=x2−9x−3 enter your answer in the boxes.

ANSWER



EXPLANATION

The given function is



When we plug in x=3 into this function, we obtain,



This means that the function is discontinuous at x=3.

We need to simplify the function to obtain,



This implies that,



The graph this function is a straight line that is continuous everywhere.

To graph


we draw the graph of


and leave a hole at x=3.

See diagram in attachment.

Hence the coordinates of hole is

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
