Answer: A is the correct answer I am 100% positive
Step-by-step explanation:
We will see that f'(x) > 0, which means that f(x) is an increasing function.
<h3>
How to prove that the function is increasing?</h3>
For any function f(x), if f'(x) > 0, then f(x) is increasing for any value of x.
Here we have the cubic function:
f(x) = x³ + 4x
If we differentiate this, we get:
f'(x) = df(x)/dx = 3x² + 4.
And notice that x² is always positive, then f'(x) > 0, which means that f(x) is an increasing function.

Answer:
7650 W-h
Step-by-step explanation:
1 day = 24 hrs
4 days and 6 hours = 4(24) + 6 = 102 hours
given
24 hrs (i.e 1 day) ------> consumes 1800 W-h
1 hour ------> consumes 1800/ 24 = 75 W-h
102 hrs (i.e 4 days 6 hrs) = 75 W-h x 102 = 7650 W-h
The answer will be option 6. angle.
Answer:
7.8856
