Answer:

domain x ≥ 7

range y ≥ 9

The 3rd answer

Step-by-step explanation:

* Lats talk about the domain and the range of the function

- The domain is the all values of x which make the function is defined

- The range is all the values of y got from the defined values of x

- In the square roots or any even roots the value under it must be

 greater than or equal to zero ( the even roots for negative values is

 undefined)

* Lets solve our problem

∵ f(x)=\sqrt{x-7}+9

- In this function we must chose the values of x which makes

 x - 7 zero or positive value

∴ Let x - 7 ≥ 0

- Now solve the inequality

∵ x - 7 ≥ 0 ⇒ add 7 to the both sides

∴ x ≥ 7

- The domain of the function is the values of x

∴ The domain of the function is x ≥ 7

- Lets use the first value of x to find the first value of y

∵ x = 7

∴ f(7) = √(7 - 7) + 9 = √0 + 9 = 9

- The first value of the range is 9

∵ The range is values of y corresponding to the values of x

∴ The range of the function is y ≥ 9

* The domain x ≥ 7

 The range y ≥ 9

Find the x-values for which f(x) = g(x)<br> if you know that f(x) = x2 and g(x) = 9.
Juli2301 [7.4K]

Answer:

For the values of x  = 3 and x = -3 the given functions f(x) = g(x)

Step-by-step explanation:

Here, the given functions are

f(x)  = x^{2} \\g(x) = 9

Now, given f(x)  = g(x)

⇒ x^{2}   = 9

or, x = \sqrt{9}   \implies x  = 3, -3

Hence, for the values of x  = 3 and x = -3 the given functions f(x) = g(x)

Step-by-step explanation:

  14 yd  1 ft  7 in

+  16 yd 2 ft 19 in

-------------------------

  30 yd  3 ft  26 in

26 inches is 2 feet and 2 inches ---> 30 yd  5 ft  2 in

5 feet is 1 yard and 2 feet ---> 31 yd  2 ft  2 in
