Answer:
The value of x = -1 makes the denominator of the function equal to zero. That is why this value is not included in the domain of f(x)
Step-by-step explanation:
We have the following expression
Since the division between zero is not defined then the function f(x) can not include the values of x that make the denominator of the function zero.
Now we search that values of x make 0 the denominator factoring the polynomial
We need two numbers that when adding them get as a result -1 and when multiplying those numbers, obtain -2 as a result.
These numbers are -2 and 1
Then the factors are:
We do the same with the numerator
We need two numbers that when adding them get as a result 4 and when multiplying those numbers, obtain 3 as a result.
These numbers are 3 and 1
Then the factors are:
Therefore
Note that only if
So since is not included in the domain the function has a discontinuity in
Not equivalent expression is validated so I think it’s second one bye
<span>(x - a)^2 + (y - b)^2 = c^2
</span>above equation is the general equation for the circle. In that, a and b are center of the circle and c is the radius of the circle.
let's change the equation to general circle equation
(x - 3)^2 + (y - 5)^2 = 25
<span>(x - 3)^2 + (y - 5)^2 = 5^2
</span>
center (3 , 5)
x = 3
y = 5
