Solution by Steps
step 1
To find the derivative of the function f(x)=x2+3x+5f(x) = x^2 + 3x + 5, we will apply the power rule to each term
step 2
The derivative of x2x^2 with respect to xx is 2x2x
step 3
The derivative of 3x3x with respect to xx is 33
step 4
The derivative of the constant 55 with respect to xx is 00
step 5
Combining the derivatives from steps 2, 3, and 4, we get the derivative of the function f(x)f(x): f(x)=2x+3f'(x) = 2x + 3
Answer
f(x)=2x+3f'(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 xnx^n is nxn1nx^{n-1}. Constants differentiate to zero.
