"By sketching appropriate graphs (one of them a straight line) show that the function(adsbygoogle = window.adsbygoogle || []).push({});

f(x) = 2sin(x) - 3x + 2

has only one real root."

this one confuses me from the word go. how can you sketch a straight line of that function when it has sin as part of it?
