Suppose that f(2)=4 and that =0 for all x. must f(x)=4 for all x? give reasons for your answer.

Yes. If f'(x) = 0 everywhere, then the graph of f(x) is a horizontal line.

If f(2) = 4, then f(x) = 4 for any x.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
