Question

The point (–3, –5) is on the graph of a function. Which equation must be true regarding the function?

Answer 1

Answer:

so the correct answer is a. f(-3)=-5.

Step-by-step explanation:

Answer 2

So the question is what does the point (-3, -5) correspond to on the graph of the function. If we have a point on a graph in the Cartesian coordinate system then that point consists of coordinates (x, y). In other words, y=f(x) and x so (x, f(x)) where x is a x-coordinate and y=f(x) is y-coordinate. So if we have a point (-3, -5) the corresponding coordinates are x=-3 and y=f(x)=-5. So it must be true that y=f(-3)=-5. So the correct answer is a. f(-3)=-5.
