Expert Solution
Step 1 Concept, how we calculated from graph
we just simply calculate from the graph
suppose we have find function at x = a. So, we can write it f(a) means putting the value of a in the place of x we can find the value of function.
From the graph, we can simply look
f(2) means function at x intercept or in the simple word what is the value of y when x has some value.
similarly we find remaining.
So, from the graph we calculated -
f(2) = 7 (the height(value of y) of the graph when x =2)
f(5) =6 (the height(value of y) of the graph when x =6)
It's net change between at x=2 and x=5 is equal to -
f(5) - f(2)
