1103076611 Level: CThe graph shown in the picture is graph of the function:f(x)=sin|x|f(x)=|sinx|f(x)=|cosx|f(x)=cos|x|
1103076610 Level: CThe figure shows the graph of the function:f(x)=cos(−2x)f(x)=−cos2xf(x)=|cos2x|f(x)=−|cos2x|
1103076609 Level: BIdentify the function shown in the graph.f(x)=−sin(x+π4)f(x)=−sin(x−3π4)f(x)=cos(x+π4)f(x)=sin(x−π4)
1103076608 Level: CIdentify the function shown in the graph.f(x)=−sin(−2x)f(x)=−sin2xf(x)=|sin2x|f(x)=sin|2x|
1003076607 Level: BIf we reflect the graph of the function f(x)=cosx over the x-axis, we get the graph of the function:g(x)=−cosxg(x)=sinxg(x)=cosxg(x)=−sinx
