Step 1: Recall that the antiderivative of a function f(x) is a function F(x) such that F'(x) = f(x). To find the antiderivative of f(x) = 5x^4, we use the power rule for integration.
Step 2: The power rule for integration states that for any term x^n, its antiderivative is (x^(n+1))/(n+1) + C, where C is the constant of integration. Apply this rule to f(x) = 5x^4.
Step 3: Integrate 5x^4. The exponent 4 increases by 1 to become 5, and the coefficient 5 is divided by the new exponent. This gives (5x^5)/5 + C, which simplifies to x^5 + C.
Step 4: Use the given condition F(0) = 1 to solve for the constant C. Substitute x = 0 into F(x) = x^5 + C, which gives 1 = 0^5 + C. Simplify to find C = 1.
Step 5: Substitute C = 1 back into the antiderivative to get the final function F(x) = x^5 + 1. This is the antiderivative that satisfies the given condition.
