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