What are the domain and range of f(x)=log(x-1)+2?

Domain =

Range =

Step-by-step explanation:

Here, the given function,

Since log( negative number ) = not defined

Also,

Hence, f(x) is defined if x - 1 > 0

⇒ x > 1

Thus, f(x) is defined for all the values that are greater than 1,

⇒ Domain of f(x) = All real number greater than 1,

=

Now, for the interval ,

f(x) can be any real number.

Thus, the range of the given function =

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
