Derivatives Practice Problems - Power Rule
Problem: Derivative Power Rule #1
Find the derivative f'(x) of:
\Large{f(x) = 5x^3+2x^2-7x+1}
Step 1:
We can use the derivative power rule to find the derivative of the given function. We have:
{f'(x) = 5(3)x^{3-1}+2(2)x^{2-1}-7(1)x^{1-1}}
Notice that we brought down the exponent, and subtracted the exponent by 1 for each term.
Step 2:
Now, after simplifying, we have:
\large{f'(x) = 15x^2+4x-7}
This is our final answer for the derivative.
