Question

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

Answer 1

Answer:

f(-3)=-5

The problem:

(-3,-5) on the graph of f implies which of the choices:

A) f(-3)=-5

B) f(-3,-5)=-8

C) f(-5)=-3

D) f(-5,-3)=-2

Step-by-step explanation:

If the name of the function is f and (-3,-5) is on the graph of f, then you can conclude the value y=-5 corresponds to x=-3.

In other words, the value f(x) is -5 when x=-3.

f(x)=-5 when x=-3 just means f(-3)=-5.

In short, (a,b) on f means that f(a)=b.
