Question

Which of the following is the graph of f(x) = cos(x)?

Answer 1

cos x has an amplitude of 1

Answer 2

dis simply means cox starts from 1 on d y axis

Answer 3

It is important to remember that

\[\large cos(0) = 1\]

So this means it will begin at a y-intercept of 1

And we can also remember that

\[\large cos(\pi/2) =cos(90) = 0\]
and
\[\large cos(3pi/2) = cos(270) = 0\]

So look for all those attibute in your graph choices
