1. The function(x)=x-1 has a discontinuity, say where and justify the response. Classify the discontinuity as essential, removable, or infinite. If the discontinuity is removable, rewrite the function so that it is continuous at all reals

Q: Find a function in general form with a vertex at (-1, -2) and passes through (3, 6). Hint: Start…

A:

Q: Explain why a function with a removable discontinuity is not differentiable at that discontinuity

A:

Q: f (x) = x + 2x³ – x² – 2 %3D

A: Given: Determine if the given function is continuous at every real number f(x)=x4+2x3-x2-2
