Find all antiderivatives of each following function: $$f(x)=9 x^{8}$$

Short Answer

Expert verified
The antiderivative of \(f(x) = 9x^8\) is \( x^9 + C \).

Step by step solution

01

Identify the function to be integrated

The function given for finding the antiderivative is \(f(x) = 9x^8\).
02

Use the power rule for integration

The power rule for integration states that the antiderivative of \(ax^n\) is \( \frac{a}{n+1} x^{n+1} + C \), where \(C\) is the constant of integration. Here, \(a = 9\) and \(n = 8\).
03

Apply the power rule

Using the power rule, we integrate \(9x^8\):\[ \frac{9}{8+1} x^{8+1} + C = \frac{9}{9} x^9 + C = x^9 + C.\]
04

Write the general antiderivative

Thus, the general antiderivative of the function \(f(x) = 9x^8\) is \( x^9 + C \).

power rule for integration
To find the antiderivative of a function like the one given, we use the power rule for integration. The power rule is a fundamental principle in calculus. It helps us integrate functions of the form \(ax^n\). Here is how it works:

The formula for the power rule is \(\frac{a}{n+1} x^{n+1} + C\), where:
