Look at the following function:
What is the domain of the function?
To solve the problem of finding the domain of the function , we need to ensure the denominator is not zero.
Here is the step-by-step solution:
Step 4: The calculated value is the value that makes the denominator zero. Hence, the domain of the function consists of all real numbers except .
Therefore, the domain of the function is all real numbers such that .
The correct choice from the multiple choices is: .
The domain of the function is .
Given the following function:
\( \frac{5-x}{2-x} \)
Does the function have a domain? If so, what is it?
Division by zero is undefined in mathematics! When the denominator equals zero, the function has no value at that point, so it's excluded from the domain.
Double-check your algebra! For , add to both sides, then divide by 2. You should get .
The domain is . The union symbol ∪ connects two intervals that exclude the restricted value.
Domain = all possible x-values (input). Range = all possible y-values (output). For rational functions, we find domain by avoiding zero denominators.
Yes! If the denominator has multiple factors like , then both x = 1 and x = -3 would be excluded from the domain.
