Question

Find the domain and range of the function f(x )=5x+3/7x-5

Answer 1

Step-by-step explanation:

Domain means what values are defined for the expression and what values make it undefined.

It is a known fact that division by 0 is undefined

so we want

the value at which 7x-5 becomes 0 so we can exclude that

if we put 7x-5=0

then x is 5/7

so the domain of your function is

• X belongs to all real number except 5/7

Range means all the possible values the expression or function can give you

in your expression

range is all real numbers.

Because your function can give all real numbers as answers.
