D.
you cannot have a negative amount of rainfall, so the predicted value of -32.4cm doesn't make sense.
H'(x) = 2f'(x)
h'(1) = 2*f'(1) = 2*4
h'(1) = 8
-19.59 is your answer because u do PEMDAS and that would be 8.1*(-1.9) which gives you -15.39 Then you do -4.2+-15.39 and you would get -19.59
0.4 / 2 = 0.2
1/0.2 = 5
2/5 is the answer
