Using the graph of the quadratic function, identify the domain

Choice B)  -infinity < x < infinity

Explanation:

The parabola goes on forever to the left and to the right. We can plug in any x value without worrying about something as a division by zero error. So any real number will work.

Writing -infinity < x < infinity refers to the entire number line, which is the set of all real numbers.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
