Question 4 which is the equation of the following graph? f(x) = 3sin x f(x) = 2sin x f(x) = 3cos x f(x) = 2cos x

Hello!

The graph of f(x) = sin(x) is an odd function, while the graph of f(x) = cos(x) is an even graph. As shown on the graph above, this graph is even because it is symmetric with respect to the y-axis.

Also, the range of this function is -3 ≤ y ≤ 3, this tells us our amplitude. which is 3. Amplitude is the maximum displacement on the graph of a function.

Therefore, the equation of this graph is choice D, f(x) = 2cos x.

oof

step-by-step explanation:

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
