Are you saying that function g(x) is not increasing for interval 2 < x < 3?

note on $2 < x < 3$, $g'(x) = f(x) < 0 \implies g(x)$ is decreasing. Last edited by skipjack; July 23rd, 2018 at 11:18 AM.

But at that interval for higher value of $x$ we get higher value of $f(x)$, but never mind. Can you just do for D) please? That would be great. Last edited by skipjack; July 23rd, 2018 at 10:32 AM.
