What is the domain and range of the function

Option d is correct.

Domain = all real number

range = positive real numbers

Step-by-step explanation:

Given the function:

Domain of the function is all real numbers except where the expression is undefined.

In this case, there is no real number that makes the expression undefined.

Domain of f(x) = = {a | a∈R}

Range is the set of all valid  f(x) values.

Therefore, Domain is all real number and the range of function is positive real number

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
