Answer:
[tex]x=\frac{-5}{2}[/tex] is the value excluded from domain.
Ad range will be all real numbers.
Step-by-step explanation:
We have been given a function:
[tex]f(x)=\frac{x+3}{2x+5}[/tex]
Domain are the values x will take and range are the values that y will have.
And function should remain defined it should not be undefined.
We know that function becomes undefined if denominator becomes zero.
At [tex]x=\frac{-5}{2}[/tex] function becomes undefined therefore
[tex]x=\frac{-5}{2}[/tex] is the value excluded from domain.
Ad range will be all real numbers.
The domain of the function will be Real except for negative 5/2. Then the range of the function will be a real number.
What are domain and range?
The domain means all the possible values of x and the range means all the possible values of y.
The function is given below.
f(x) = (x + 3) / (2x + 5)
The function is not defined at 2x + 5 = 0,
Then we have
2x = - 5
x = - 5/2
Then the domain of the function will be Real except for negative 5/2.
The range of the function will be a real number.
More about the domain and range link is given below.
