Answer:

B. (-4-2)

Step-by-step explanation:

since the numerator is one you can divide -8 by the denominator of each fraction. -8/2 = -4, -8/4 = -2

(-4-2)

You have to make sure you distribute the -8 to all parts inside the parenthesis for it to be right.

i hope this helps :)

The sequence defines a function $f(x)=4.(3)^{x-1}$

Domain : $\{1,2,3,4,5\}$

Range : $\{4,12,36,108,324\}$

Explanation:

A sequence defines a function if it is the set of natural numbers.

Thus, the function is given by

$f(x)=4.(3)^{x-1}$

The sequence can be determined by substituting the values for x.

For $x=1$ ,

$f(1)=4(3)^{0}=4$

For $x=2$ ,

$f(2)=4(3)^{1}=4(3)=12$

For $x=3$ ,

$f(3)=4(3)^{2}=4(9)=36$

For $x=4$ ,

$f(4)=4(3)^{3}=4(27)=108$

For $x=5$ ,

$f(5)=4(3)^{4}=4(81)=324$

Thus, from these the domain and range of a function can be determined.

The domain of a function is the set of independent values, which are generally the x-coordinates.

Domain of a function is $\{1,2,3,4,5\}$

The range of a function is the set of dependent values obtained by substituting the values for x.

Range of a function is $\{4,12,36,108,324\}$
