For 
to be conservative, we need to have
Integrate the first PDE with respect to 
:
Differentiate with respect to 
:
Now differentiate 
with respect to 
:
So we have
so is indeed conservative.
\sqrt{10}-\sqrt{14}+\sqrt{15}-\sqrt{21}
Answer:
B. 3(2^x)
Step-by-step explanation:
3(2^x) is the only function that yielded the given outputs when the inputs were plugged in.
Step-by-step explanation:
put some x values into the equation
i.e : -2, -1, 0 ,1 ,2
3/5 (-2) +2 = 4/5 (-2, 4/5)
3/5 (-1) +2 = 7/5 (-1, 7/5)
3/5 (0) +2 = 2 (0, 2)
3/5 (1) +2 = 2.6 (1, 2.6)
3/5 (2) +2= 3.2 (2, 3.2)
Then plot these on the graph as corodinates with the x values
1 on top of the 3 ... you put the one on top and the 3 on the bottom and its one third
