# 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)

((14x3/2)/3)+(x5/5)+C

Then I tried substituting -5 for x and this is what I got, but it said that it won't accept the answer because:

(14(-5)^(3/2))/3-625

"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!
