Consider the two functions shown below.

loris [4]

ANSWER

B. The functions f(x) and g(x) because f(g(x))=g(f(x))=x

EXPLANATION

The given functions are:

$f(x) = 2x - 2$

and

$g(x) = \frac{1}{2}x + 1$

If f(x) and g(x) are inverses, then

f(g(x))=x

$f(g(x))=f( \frac{1}{2} x + 1)$

$f(g(x))=2( \frac{1}{2}x + 1) - 2$

Expand the parenthesis to obtain,

$f(g(x))=x + 2- 2$

$f(g(x))=x$

Also,

$g(f(x)) = g(2x - 2)$

$g(f(x)) = \frac{1}{2} (2x - 2) + 1$

$g(f(x)) = x - 1+ 1$

$g(f(x)) = x$

Hence f(x) and g(x) are inverses

Evaluate and match each expression on the left to its value on the right, when x=8 and y=3.

Crank

Answer:

12-y------------> 9

3x-y------------>21

4y-10----------->2

1/4 xy-----------> 6

Solution,

Given,

X=8

y=3

Now,

$1. \: \: 12 - y \\ \: \: \: = 12 - 3 \\ \: \: = 9 \\ 2. \: \: 3x - y \\ \: \: = 3 \times 8 - 3 \\ \: \: = 21 \\ 3. \: \: 4y - 10 \\ \: \: = 4 \times 3 - 10 \\ \: = 12 - 10 \\ \: \: = 2 \\ 4. \: \: \frac{1}{4} xy \\ \: \: = \frac{1}{4} \times 8 \times 3 \\ = 6$

hope this helps...

Good luck on your assignment...
