A function and it's inverse function, when graphed, will be symmetrical across the line y=x.
Without seeing your graphs, I can't tell you if it's g or h. Look for the function which mirrors 'f' across y=x, which is a diagonal line passing through the origin (0,0) of the graph.
Well each angle in a rectangle is 90°, so if x is an angle, it's 90°
I hope that helps!
It’s -3 degrees . Count forwards two times ....
