Question

What is the value of the function when X equals four? on a coordinate plane.

Answer 1

From the given graph the x-intercept is 2 and y-intercept is -1 .

So, equation of line in intercept form is :

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

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

Now, putting x = 4 in above equation, we get :

`y = (4-2)/(2)\\\\y = 1`

Therefore, the value of function at x =4 is 1 .
