Answer:
6x²+18x+12
Step-by-step explanation:
(-3x-6)(-2x-2)
=-3x(-2x-2)-6(-2x-2)
=6x²+6x+12x+12
=6x²+18x+12

Step-by-step explanation:
6 squared is basically the same thing as six times six so therefore ur answer is 36
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.
