To find the antiderivative F(x) of the function f(x) = 5x^4, we need to apply the power rule for integration. The power rule states that the antiderivative of x^n is (x^(n+1))/(n+1) + C, where C is the constant of integration.
Apply the power rule to f(x) = 5x^4. Increase the exponent by 1, which gives us x^5, and divide by the new exponent. This results in (5/5)x^5 = x^5.
Now, we have F(x) = x^5 + C, where C is the constant of integration. To find the value of C, use the condition F(0) = 1.
Substitute x = 0 into F(x) = x^5 + C, which gives us F(0) = 0^5 + C = C. Since F(0) = 1, we have C = 1.
Thus, the antiderivative that satisfies the given condition is F(x) = x^5 + 1.
