This is just substitution. so 3(2(3)-4(1/2)+3(-2/3)= 3(6-2-2)= 3(2) = 6. Basically you plug in the values they gave you for the variables and then just solve one step at a time
Based on the graph,
f(x) = 1/2x+3
g(x) = -x+4
so, h(x) = -1/2 x +7
Since h'(x) is the derivative or slope of h(x) and h is a line,
h'(x) = -1/2, Answer C.
