You must make c the number that makes that true. Plug in 1 for x, 10 for y then solve for c.

## Let f(x)=2x^2-4x+5

Let f(x)=2x^2 -4x+5.Suppose that F is an antiderivative of f such that

F(1)=10.Find F(x).

I think the anti derivative is as follows:

F=2**∫x^2 dx -4∫x dx + 5∫1 dx**

**F=2.x^3/3-4.x^2/2+5.x+c**

**But when I plug in 1 in the F i.e F(1) ...I do not get 10 as given in the problem.Can somebody pls help me?**
