x ≠ 7  

(x < 7 or x > 7)

{x : x < 7 U x > 7}

Step-by-step explanation:

f o g = f [ g(x) ]

This means replace the x of f(x) with g(x):

f o g =

domain = set of values that go into the function

Therefore, for f o g, domain is x ≠ 7 as the function is undefined when x = 7.

So this can be written as (x < 7 or x > 7)  or  {x : x < 7 U x > 7}

y= -

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.
