Question 409397: I'm not quite sure what the means:
The graph of f(x) = -5 falls into which quadrants?
I do understand the concept of a graph and quadrants though. I just don't understand the equation.

The graph of f(x) = -5 falls into which quadrants?
:
It would look like this: y = -5

The xy-plane (usually named Cartesian plane, after mathematician Rene Descartes) is just like a number line, except in two dimensions. The function f%28x%29+=+-5 is similar to saying y+=+-5 since y is a function in terms of x. However this is not always the case!

The graph y+=+-5 is a horizontal line in which the y-coordinate is -5, regardless of x:

graph%28200%2C+200%2C+-10%2C+10%2C+-10%2C10%2C+-5%29

The graph lies in the third and fourth quadrants (look in your textbook or online which quadrant is which).
