what is the equation of the midline of the function f(x)= 5.6sin(1.2x-2.3)+1.8
the ansewer options are
y=-2.3
y=-1.8
y=1.8
y=2.3
A sine function on its own has a maximum of 1 and a minimum of -1 with a midline of 0; so what value does f(x) have if you replace the sine function in it by 0?
oh so it would just be 1.8 then right
Right.
awsome ty :D
