Compute the derivative of the function f(x)=x2+3x+5.
Solution by Steps
step 1
To compute the derivative of the function f(x)=x2+3x+5, we will use the power rule for differentiation, which states that the derivative of xn is nxn−1
step 2
Applying the power rule to each term: f′(x)=dxd(x2)+dxd(3x)+dxd(5)
step 3
Differentiating each term separately: f′(x)=2x+3+0
Answer
f′(x)=2x+3
Key Concept
Power Rule for Differentiation
Explanation
The derivative of a polynomial function is found by applying the power rule to each term, which involves bringing down the exponent as a coefficient and subtracting one from the exponent. Constant terms differentiate to zero.
