What is the domain and range of the equation y=500(1.08)^x

(x) is an element of a real number. This means it could be an integer, fraction or irrational number.

* As x approaches infinity, y approaches infinity.

* As x approaches minus infinity, y approaches 0.



Domain:

(x) is an element of a real number

Range:

y>0

answer:

let see.

numbers which are bigger than 0 are defined as positive numbers and have a prefix of + (plus).

numbers which are smaller than 0 are defined as negative numbers and have a prefix of - (minus).

let say number a is equal to the expression,

a=3xy

since y is negative we can change its prefix to -,

a=3x\cdot(-y)

any number (in this case 3x) multiplied by negative number will produce a negative number.

therefore the sign or prefix of number a will be -.

hope this .
