# How do you write an equation of y=cosx with 1.5 units to the right?

$y = \setminus \cos \left(x + 1.5\right)$
New equation of $y = \setminus \cos x$ is obtained by shifting x-axis by $1.5$ unit to the right keeping y-axis fixed.
The transformed equation will be obtained by setting $x = x + 1.5$ in given equation as follows
$y = \setminus \cos \left(x + 1.5\right)$
