f(x) = 3 sin x, g(x) = sin 2x; h(x) = (f + g)(x)

@UnkleRhaukus @ash2326

unklerhaukus · Answer

(f + g)(x)=f(x)+g(x)

unklerhaukus · Answer

lets start with a the y-intercept $(0,y_0)$

set x=0
$$f(0) = 3 \sin 0= 0$$
$$g(0) = \sin 2\cdot 0= 0$$

$h(0) = 0\qquad\rightarrow (0,0)$ is a point

unklerhaukus · Answer

try some other points along the x axis

anonymous · Answer

can someone tell me what the answer is? @UnkleRhaukus  all the graphs have (0,0)

anonymous · Answer

@mandonut can u help?

unklerhaukus · Answer

thats true, what happens if x=3pi/2?

anonymous · Answer

f=-3
g=0
h=-3

so what would the other point be?

anonymous · Answer

here's a hint... check their amplitudes.. that should reduce your choices....

anonymous · Answer

i'll be back...
gotta go... sorry....

anonymous · Answer

what are amplitudes again @dpaInc
