Question

Which of the functions could be represented by the graph shown?

Answer 1

I have the answer but don't understand why

Answer 2

So wat hints do you have? The answers cant be negative.

Answer 3

non of them!

Answer 4

Well, you could try plugging in values and seeing what happens. Since on the graph \[f(\frac{\pi}{2})=0\], if the function gives any other value it can't be that function.

\[\sqrt{\sin{\frac{\pi}{2}}}=1\], so it can't be A

\[\sin^2(\frac{\pi}{2})=1\], so it can't be B

\[\sin{\sqrt{\pi/2}}=0.95002...\], so it can't be C

\[\sin((\pi/2)^2)=0.624...\], so it can't be D

\[\sin{(\pi/(\pi/2))}=\sin{2}=0.909...\]
Is there a "none of the above" answer? This question seems flawed.

Answer 5

3pi/2 doesnt exist on your graph
