Answer: Domain = (-1, \infty)

Range = (-\infty, \infty)

Step-by-step explanation:

Here, the given function,

f(x) = log(x-1) + 2

Since log( negative number ) = not defined

Also,

log(0) = -\infty

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,

= (1, \infty)

Now, for the interval (1, \infty),

f(x) can be any real number.

Thus, the range of the given function = (-\infty, \infty)

Find the answer to 1/8 + 7/12
dangina [55]

Answer: 17/24

Step-by-step explanation: Notice that 1/8 and 7/12 are unlike fractions. Our first step when adding unlike fractions is to get a common denominator.

The common denominator of 8 and 12 will be the least common multiple of 8 and 12 which is 24. To get a 24 in the denominator of 1/8, we multiply the numerator and the denominator by 3 which gives us 3/24. To get a 24 in the denominator of 7/12, we multiply the numerator and the denominator by 2 which gives us 14/24. Now we're adding like fractions.

3/24 + 14/24

To add like fractions or fractions that have the same denominator, simply add the numerators and keep the original denominator.

So here, if we add the numerators we have 3 + 14 which gives us 17. We put this over our original denominator which is 24. So we have 17/24.

So 1/8 + 7/12 is 17/24.

Find the product of 4/5 and 5/12 put in simplest form
kotegsom [21]

Hello!

The answer is 20/60 simplest form is 1/3

To get 20/60 you must multiply the Numerator by Numerator (4*5) and Denominator by Denominator (5*12). Your answer will be 20/60.

To get 1/3 you must simplify a number that can go into 20 and 60 (which is 10). Divide 20/10 and 60/10 and get 2/6. Simplify 2/6 by 2 and get 1/3.
