Question

What are the domain and range of the function?
A
B
C
D

What are the inputs of the function below?
A
B
C
D

Answer 1

Log function can't take negative values. So 5-xmust be greater then 0, that is

5-x>0

-x>-5

x<5

And the range is all real numbers .

For the second question input values are represented by x. And the values of x are -8 2 4 6

So the correct option is third option .

Answer 2

Answer:

Step-by-step explanation:

First, we know that log(0) goes to minus infinite, so the domain will be such than we never have a zero inside the logaritm, and we have:

Log (5 - x) this means that x can not be bigger than 5, then the correct option is the first one, x < 5

In the second problem we have a table of x and f(x) where the input values are the x, and the output values are the ones of f(x), (the values of x are the ones upside) -8, 2, 4 and 6, so the correct option here is the third option
