If the point (4, -1) is a point on the graph of f, then f(4) = -1

First blank = 4

second blank = -1

Step-by-step explanation:

The given point: (4, -1)

From the point: the coordinate tells us x = 4, y = -1

For a graph of function f, f(x) is the same as y

To represent the point (4, -1) as a funtion of x (that is f(x)), we will replace x in f(x) with the value of the x coordinate. The result when we replace it will the value of the y coordinate

when x = 4

f(4) = the value of the y coordinate

f(4) = -1

To complete the blanks:

If the point (4, -1) is a point on the graph of f, then f(4) = -1

First blank = 4

second blank = -1
