Consider the function
I've been trying to figure out this problem for some time now.
Consider the function f(x)=x4+7√(x).
Let F(x) be the antiderivative of f(x) with F(1)=-5
Then F(x) =_______________
I found the antiderivative of f(x)
Then I tried substituting -5 for x and this is what I got, but it said that it won't accept the answer because:
"Can't raise a negative number to a non-integer power"
And I tried substituting -5 for C, but that was also incorrect.
I don't get what it is asking. Many thanks to you if you can help!
