Use the graph below to fill in the blank with the correct number: f(1) =

Step-by-step explanation:

We are given a graph with four points on the graph with coordinates as following:

(-3,0)

(-2,2)

(0,1) and

(1,-2).

We need to find the value of function f(x) at x=1 that is f(1) =?

That means we need to find the y-coordinate of the point, where x coordinate is at 1.

We can see tat fourth point on the graph (1,-2) has x-coordinate at 1 and y-coordinate at -2.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
