A hole occurs where a factor \( (x - c) \) cancels from both the numerator and denominator. Substitute \( x = 4 \) 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 \( x = 4 \) rather than a vertical asymptote!
For \( f(x) \) to possess a removable discontinuity at \( x = 4 \), the numerator must also have \( (x - 4) \) as a factor. Setting the numerator equal to 0 at \( x = 4 \) reveals the unknown coefficient. Factoring both the numerator and de...

The system of equations below is given by: \[ y = a x^2 + b x + c \] \[ y = m x + k \] where \( a \), \( b \), \( c \), ...
Consider the system of equations below: $$\begin{cases} 4x - 3y = 5 \\ 2x + y = 5 \end{cases}$$ If $(x, y)$ is the solut...
