Find the domain of each rational function. $$f(x)=\frac{x+7}{x^{2}+49}$$

Short Answer

Expert verified
The domain of the function \(f(x) = \frac{x+7}{x^{2}+49}\) is all real numbers.

Step by step solution

01

- Identify the denominator

The denominator of the given function is \(x^{2}+49\).
02

- Set the denominator equal to zero

Equating the denominator to zero gives \(x^{2}+49=0\).
03

- Solve the equation

To find the root of this equation, subtract 49 from both sides \(x^{2}=-49\).
04

- Final result

The above equation has no real solutions as the square of any real number cannot be negative. This means there are no x-values that will make the denominator zero and therefore, the function \(f(x)=\frac{x+7}{x^{2}+49}\) is defined for all real numbers.
