Answer:

$y=-\cos x$

Step-by-step explanation:

The given trigonometric graph is symmetric about the y-axis.

This means it is a cosine function.

The basic is symmetric about the y-axis and has a y-intercept of 1.

Its range is $-1\le y\le1$

Since the given graph has y-intercept at -1 with the same range, it is the parent cosine function reflected in the x-axis.

Therefore its equation is $y=-\cos x$
