Domain and range of a non function
WebEXAMPLE 2. Find the domain and range for the function f (x)=\frac {1} {x+5} f (x) = x+51. Domain: The function f (x)=\frac {1} {x+5} f (x) = x+51 is not defined for x=-5 x = −5 since this value would produce a division by 0. Therefore, the domain of the function is all real numbers with the exception of -5. Range: No matter how big or how ... WebWhen you see the white dot, it just means that the function is not defined at that point. So, $f (-5)$ is undefined, also $f (-1)$ is undefined, but $f (3) = 0$. Also, the domain does not stop at $x = 8$; it goes all the way to $\infty$. Some textbooks add …
