Why does the formula image serve as a link to some strange site and why is there another hidden link to the same site?

I dont know how to use the information in the problem to solve it .

Apply g to 0.85. If the result is less than or equal to -2, apply the first line in the definition of f to the result. Otherwise, apply the second line.

It is bigger than -2 ,so f(.80)=2(.80)+3 ,right ?

The greatest integer not exceeding 0.85 is 0, so g(0.85) = 0. Yes, 0 > -2, so (f ∘ g)(0.85) = f(g(0.85)) = f(0) = 2 * 0 + 3 = 3.
