Answer:

The range of the function (g\°f)(x) is

B.  is all real numbers except y=0

Step-by-step explanation:

Given functions:

f(x)=x+3

g(x)=\frac{1}{x}

To find the range of (g\°f)(x).

Solution:

In order to find (g\°f)(x) , we will plugin f(x) in function g(x).

(g\°f)(x)=g(f(x))

(g\°f)(x)=\frac{1}{x+3}

The graph of the function (g\°f)(x) shows that

1) As x approaches -3 (but never touches the line x=-3), y tends to positive or negative infinity.

2) As y approaches 0 (but never touches the line y=0) , x tends to positive or negative infinity.

Thus, the range of the function is all real numbers except y=0

Answer:

!. Scale factor = 5

2. Scale factor = \frac{1}{5}

Step-by-step explanation:

scale = \frac{length in drawing}{actual length}

1. To increase the numbers, let the scale factor be \frac{5}{1} = 5. So that;

0.05 x 5 = 0.25

\frac{1}{2} x 5 = 0.5 x 5 = 2.50

7 x 5 = 35.00

13 x 5 = 65.00

25 x 5 = 125.00

102 x 5 = 510.00

2. To decrease the numbers, let the scale factor be \frac{1}{5}. So that;

0.05 x \frac{1}{5} = 0.01

\frac{1}{2} x \frac{1}{5} = 0.5 x \frac{1}{5} = 0.10

7 x \frac{1}{5} = 1.40

13 x \frac{1}{5} = 2.60

25 x \frac{1}{5} = 5.00

102 x \frac{1}{5} = 20.40
