A hole occurs where a factor \( (x - c) \) cancels from both the numerator and denominator. Substitute \( x = 3 \) into the numerator to find the missing constant.
Desmos Shortcut: Enter \( f(x) \) into Desmos with a slider for the unknown constant. Slide it until the graph shows an open circle at \( x = 3 \) rather than a vertical asymptote!
For \( f(x) \) to possess a removable discontinuity at \( x = 3 \), the numerator must also have \( (x - 3) \) as a factor. Setting the numerator equal to 0 at \( x = 3 \) reveals the unknown coefficient. Factoring both the numerator and de...

How many distinct real solutions does the following equation have? \[ \frac{x}{x-4} - \frac{4}{x+4} = \frac{32}{x^2-16} ...
If \( x > 1 \) and the equation \[ \frac{\sqrt[3]{x^a}}{\sqrt[4]{x^b}} = x^2 \] is true, and it is also given that \( 2a...
Consider the system of equations below: $$\begin{cases} 2x + y = 11 \\ x - y = 1 \end{cases}$$ If $(x, y)$ is the soluti...
