Answer:

x = 4

Step-by-step explanation:

(33-2x)^(1/2) = x + 1

33-2x = x^2 + 2x + 1           [square both sides]

x^2 + 2x + 1 - 33 +2x = 0

x^2 + 4x - 32 = 0

(x - 4)(x + 8) = 0

x = 4

What is the domain of the following graph?
Morgarella [4.7K]

Answer:

[0,9]

Step-by-step explanation:

The domain is the first set of the ordered pair. When finding the domain you are supposed to find which x value it starts from to where it ends. The x value starts from 0 and ends and the 9th unit on the x-axis which would give us 0,9 now since both points are closed you would use these symbols [ ] to show that it is closed meaning the answer would be [0,9]

Note:

I'm sorry if this is wrong but this is what I believe the answer is.
