Find the antiderivative of

f(x) = 3x^2

Generated Graph

Solution by Steps

step 1

To find the antiderivative of the function

f(x) = 3x^2

, we integrate the function with respect to

x

step 2

The integral of

3x^2

with respect to

x

\int 3x^2 \, dx

step 3

Applying the power rule for integration, which states that

\int x^n \, dx = \frac{x^{n+1}}{n+1} + C

for any real number

n \neq -1

, where

C

is the constant of integration

step 4

Using the power rule, we get

\int 3x^2 \, dx = 3 \cdot \frac{x^{2+1}}{2+1} + C

step 5

Simplifying the expression, we have

\int 3x^2 \, dx = x^3 + C

, where

C

is the constant of integration

Answer

x^3 + C

Key Concept

Integration using the power rule

Explanation

The antiderivative of

3x^2

is found by applying the power rule for integration, which increases the exponent by 1 and divides by the new exponent, then multiplies by the coefficient.
