Option 3.
Step-by-step explanation:
In this question we have to draw a graph f(x) = |-x+8|
Its a modified form of a graph f(x) = |-x| which starts from origin, having two perpendicular lines in quadrant 1 and 2.
Then f(x) = |-x| is shifted 8 units right on the x-a xis. therefore the modified form becomes f(x) = |-x+8| as shown in the option number 3.
Option 3 is the correct answer.
