To find the antiderivative of f(x)=3x2, we need to integrate the function with respect to x
step 2
The integral of 3x2 with respect to x is given by ∫3x2dx
step 3
Using the power rule for integration, ∫xndx=n+1xn+1+C, we get ∫3x2dx=3⋅2+1x2+1+C
step 4
Simplifying, we obtain 3⋅3x3+C=x3+C
Answer
The antiderivative of f(x)=3x2 is x3+C.
Key Concept
Antiderivative (Indefinite Integral)
Explanation
The antiderivative of a function is found by integrating the function with respect to its variable. In this case, we used the power rule for integration to find the antiderivative of 3x2.
