Solution by Steps
step 1
To find the derivative of the function f(x)=x2+3x+5, we will apply the power rule to each term
step 2
The derivative of x2 with respect to x is 2x
step 3
The derivative of 3x with respect to x is 3
step 4
The derivative of the constant 5 with respect to x is 0
step 5
Combining the derivatives from the previous steps, we get the derivative of the function: f′(x)=2x+3
Answer
f′(x)=2x+3
Key Concept
Power Rule for Differentiation
Explanation
The power rule states that the derivative of xn with respect to x is nxn−1. Applying this rule to each term in the function f(x)=x2+3x+5 gives us the derivative f′(x)=2x+3.
