For this case we have the following equations:
We must find 
By definition of composition of functions we have to:
So:
We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.
So, the roots are:
The domain is given by all real numbers except 0 and 3.
Answer:
x other than 0 and 3
Answer:
-1 1/3 as a mixed number (if they ask for it in simplest form, choose this one)
-4/3 as an improper fraction
Step-by-step explanation:
1. Keep, change, flip
4/5 x -5/3
2. Cross cancel the fives
4/1 x -1/3
3. Simplify
-4/3 or -1 1/3 (they're equivalent)
Answer:
<h2>7,938 Is the Area, do you need the perimiter?</h2>
Step-by-step explanation:
You have to use the Pythagorean theorem but there is a little twist here since a square has has equal sides. So:
x^2+x^2=8
2x^2=8
2/2x^2=8/2
x^2=4
√x^2=√4
x=2
The side of the square is 2.
So now the area of a square is:
Side×Side
2×2=4
The area of the square is 4 centimetres
Depends on the price of the box... we need that too
