Answer:

Only A

Step-by-step explanation:

For A, the y coordinate does represent the total cost of electricity for 4 hours. If you see the corresponding numbers on the chart, they both work. As for B, I used a proportional relationship with A to calculate if B works. Work: $120/4 hours. Divide both sides by 4 and u get $30 per hour, which means B is incorrect. C is incorrect because the answer is A.

experts, geniuses, aces and moderators .. need help on the attached. will give brainliest!!! find the derivative of e^x

STatiana [176]

To find the derivative, you must use the chain rule.

If u=x^3+2x:
dy/dx=(dy/du)(du/dx)
dy/du=d/du(e^u)=e^u=e^(x^3 + 2x)
du/dx =d/dx (x^3+2x) = 3x^2 + 2

So dy/dx=
e^(x^3+2x) * (3x^2+ 2)
