15 x 20 and 10 x 30 hope this works
3x10^-7 = 3 / (10^7) = 3 / 10000000 = 0.0000003;
A number greater then 0.0000003 is 1.
The first thing you should do in this case is to compose both functions:
f (x) = x + 7
g (x) = 1 / (x-13)
Making the composition
f (g (x)) = (1 / (x-13)) + 7
f (g (x)) = (7 (x-13) +1) / (x-13)
Answer:
The domain of the function is:
x other than 13
(option 4)
8. 8 is greater than 3 and is all the way to theeft. if it was to the right, you'd need more info
