Determine the domain of the function in the correct set notation. f(x) = 2x+6

O {x|x € R, x*–3}

O {x|x ER, x + 3}

O {x|x € R, x† 2}

O {x|x € R, x*-2}

{x|x}

Step-by-step explanation:

We are given that a function

We have to find the domain of the function in the correct set notation.

The given function is linear polynomial .

The linear polynomial is  defined for all real  values of x.

Therefore, the given function is defined for values of x.

Domain of f is given  by

{x|x}

Hence, the domain of the function in the correct set notation is given by

{x|x}

angle addition postulate

2x=56

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
