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 steps 2, 3, and 4, we get the derivative of the function f(x): f′(x)=2x+3
Answer
f′(x)=2x+3
Key Concept
Differentiation of Polynomials
Explanation
The derivative of a polynomial function is found by applying the power rule to each term, which states that the derivative of xn is nxn−1. Constants differentiate to zero.
