F is increasing, there are no jumps: if there's a jump from an a to a b
then one of the endpoints would be a limit point of F(S)
Let's simplify step-by-step.
2/5(d−10)−2/3(d+6)
Distribute:
= (2/5)(d)+(2/5)(−10)+ −2/3d+ −4
= 2/5d+−4+ −2/3d+ −4
Combine Like Terms:
= 2/5d+−4+ −2/3d+ −4
= −4/15d+−8
And your answer is...
= −4/15d+−8
