It is decreasing when the gradient of the tangent to the curve is negative.

You can work out where this is true.

If you want we can chack the answer that you get.

PLEASE NO ONE ANSWER OVER THE TOP OF ME.

THIS SHOULD BE A TEACHING FORUM - NOT A CHEAT FORUM!

JJ I am not saying you are cheating. My comment is a general one.

JJ probably doesn't know what a gradient is...

We read a function from left to right

Note that the function increases from (-inf, 0) as we go from left to right

Then from (0, 1) it does what ???

Then from (1, 2) it increases again

Then from (2, inf) it does what???

You should get two answers....see if you can get them based on the info given....

If not....let us know....
