Question

Find the derivative of the function.

Answer 1

Answer:

b. 4x

Step-by-step explanation:

We can use the power rule for derivatives, which says $\frac{d}{dx} x^n = nx^{n-1$

So, if $f(x) = 2x^2 + 1$

then $f'(x) = 4x$.

The 1 goes away because the derivative of any constant is 0.

hope this helped!

Step-by-step explanation:

We can use the power rule for derivatives, which says

So, if

then .

The 1 goes away because the derivative of any constant is 0.
