Ido not understand this!

if the composition of two functions is:



find the domain restriction. show your work

The answer to your question is: Domain (-∞, 3) U (3, ∞) or R - {3}

Step-by-step explanation:

Rational function is a function that is expressed as a fraction.

F(x) =

In rational functions, Q(x) must be different from zero.

Then

            x - 3 ≠ 0

            x = 3

Finally  

          Domain will be  R - {3}

          or   (-∞, 3) U (3, ∞)

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
