An object moving along the x axis is acted upon by a force Fx (force in x direction) that varies with position as shown. How much work is done by this force as the object moves from x = 2m to x = 8m

[In the graph, where the points are defined by (x, Fx) the relevent points are (2, 20) and (8, -10)]
Thank you so much!

W = F.d 
then you have to get the area under the graph(between the graph and x axis) to get work
If it's linear get the area of the shape under the graph(if it has some curvature use get the function then use definite integration ).
