How to Find the Domain of a Function Algebraically

WebFind the domain of function f defined by f (x) = log 2 (x 2 + 5) Solution to Example 2. The argument of log 2 (x 2 + 5) which is x 2 + 5 is always greater than zero and therefore positive. Hence the domain of the given function is given by the interval: (-∞ , +∞) Matched Problem 2 Find the domain of function f defined by: f (x) = ln (3 + x ... WebFor each number that you want to know whether or not it is in the domain, you plug in that number for x, and see if the answer makes sense. I'm going to look at the function x+5/x-3. If I plug in 0, I get 0+5/0-3, which turns into -5/3. That's a real number, so 0 is in the domain of the function. If I plug in 3, I get 3+5/3-3, which turns into 8/0. filter external emails outlook https://galaxyzap.com
