If f(x) = 2x - 3 and g(x) = |x| + 2, then (f o g)(x)

I'm guessing this is supposed to be f(g(x)). In this case when it is f of g of x, you plug in g(x) for all the values of x in f(x). So in this case it would be:

2(|x|+2)-3

Hope this helps!

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
