Answer: Yes it is!
Step-by-step explanation:
Answer:
The domain of the function should be:
'x greater than or equal to negative -5'.
Hence, option A is true.
Step-by-step explanation:
Given the expression

The domain of a function is the set of input or arguments for which the function is real and defined
We know that the value, inside the radicand, is the number found inside a radical symbol which must be greater than 0, otherwise, it would make the function undefined,
i.e.
x-5 ≥ 0
x ≥ 5
In other words, the domain of the function should be:
'x greater than or equal to negative -5'.
Therefore, the domain of the function:
x ≥ 5

Hence, option A is true.
Answer:
This is an arithmetic sequence with a common difference <em>d</em> of -9
Step-by-step explanation:
When you find out <em>d</em>, you realize the difference between the numbers to be -9. Since it is <em>d</em> and not common ratio <em>r</em>, it is an arithmetic sequence.
Answer:
B
Step-by-step explanation:
I believe it is B because it is the only one that doesnt have x values that repeat and give different answers.
Ex. For a, the x value in the first and third coords gives both 1 and 3 as answers.
Every x has to have a unique y value, so
(2,10) (3,12) is ok, but (2,10) (2,12) is not.
Sorry if this doesnt make sense haha
