Question
In Exercises $9-15$, find the domain. $f(x)=\frac{9-x}{2 x+5}$
Step 1
The function is a rational function, which means it is defined for all values of x except for those that make the denominator equal to zero. So, we need to find the values of x that make the denominator equal to zero: 2x + 5 = 0 Now, we can solve for x: 2x = Show more…
