Choose the correct equation for the function of the graph shown below. y = 1/2cos1/4x y = 1/4sinx1/2 y = 1/2 cos1/4x y = 1/4sin1/2x

first lets decide sine or cosine any ideas? hint: \(\sin(0)=0,\cos(0)=1\)

im really not sure

take a look at the graph what is y when x is 0?
anonymous
  • anonymous
i dont see when x is 0

where is 0 on the x axis?
anonymous
  • anonymous
in the middle of the crossing lines
misty1212
  • misty1212
yes at the origin \((0,0)\) so asking what is the curve at \(x=0\) is asking where does it cross the \(y\) axis

  • anonymous
i guess it'll on 0.5
misty1212
  • misty1212
yes i think so too
misty1212
  • misty1212
which tells you two things first it cant be sine, since \(\sin(0)=0\)
misty1212
  • misty1212
so it must be cosine and also since \(\cos(0)=1\) and here you have \((0.\frac{1}{2})\) the amplitude is \(\frac{1}{2}\) so there must be a \(\frac{1}{2}\) out front

so the answer is either A or C they look identical to me so maybe there is a typo somewhere in the question
