Identify Function & Point: Identify the function and the point of interest. f(x)=11−2xx2−4, we need to find limx→3f(x).
Substitute x=3: Substitute x=3 directly into the function to check if the function is defined at this point.f(3)=11−2⋅3(32)−4=11−69−4=55=1.
Calculate Limit: Since direct substitution did not result in an indeterminate form, the limit as x approaches 3 is simply the value of the function at x=3.x→3limf(x)=1.
