Question

Find the equation of the graph in function notation. Name your function "f" and use x as your variable.

Answer 1

`f(x)=(1)/(2)x-1`

Explanation:

The equation of the graph can be obtained using the formula:

`(x)/(x-intercept)+(y)/(y-intercept)=1`

From the graph, the y-intercept is -1 and the x-intercept is 2

We substitute these values to get:

`(x)/(2)+(y)/(-1)=1`

`(x)/(2)-y=1`

This implies that;

`(x)/(2)-1=y`

Or

`y=(1)/(2)x-1`

The function notation is

`f(x)=(1)/(2)x-1`
