Given the graph of f(x), determine the range of f−1(x).
11Alexandr11 [23.1K]

The graph of f(x) has a horizontal asymptote at y = 3, so its range is the interval union (-∞, 3) U (3, ∞).

The domain of its inverse is the same as the range of f, so the fourth option is correct.

For each expression,use a property to write an equivalent expression.Tell which property you used. 10:CD= 11:x+13= 12:4(2x-3)= 1

10.) DC 
community property

11.) 13+x
community property


12.) 8x-12
distributive property

13.)  (2+a)+b


14.) 4(2x+1)= 4+8x

For question 14 you can do 4×2=8x. Then do 4×1=4. It is equal. Just do distributive property for number 14 for 4(2x+1)

1. N - 80 = 40 2. 15n = 30 3. N + 284 = 350 4. 6 + 9 = 3 x n 5. N divided by 3 = 6 +1 6. 12 - 8 = n divided by 5 7. 58 x 6 = n -
kkurt [141]

Answer:

1. N=120

2. n=2

3. N=66

4. n=5

5. N=21

6. n=20

7. n=1398

8. n=5

Step-by-step explanation:

1.

N-80=40

N=40+80

N=120

2.

15n=30

\dfrac{15n}{15}=\dfrac{30}{15}

n=2

3.

N+284=350

N=350-284

N=66

4.

6+9=3\times n

15=3n

\dfrac{15}{3}=n

n=5

5.

\dfrac{N}{3}=6+1

\dfrac{N}{3}=7

N=7\times 3

N=21

6.

12-8=\dfrac{n}{5}

4=\dfrac{n}{5}

4\times 5=n

n=20

7.

58\times 6=n-(723 + 327)

348=n-1050

348+1050=n

1398=n

8.

4n+12=(7+9)\times 2

4n+12=16\times 2

4n+12=32

4n=32-12

4n=20

n=\dfrac{20}{4}

n=5

Therefore, the solutions are 1. N=120

2. n=2

3. N=66

4. n=5

5. N=21

6. n=20

7. n=1398

8. n=5
