Short Answer

what it means, in terms of limits, for a function to have a removable discontinuity, a jump discontinuity, or an infinite discontinuity at x = c

If limitlimxcf(x)f(c) then the discontinuity is known as removable discontinuity.

If limit limxc-f(x)limxc+f(x)then the discontinuity is known as jump discontinuity.

If limit limxc-f(x)= orlimxc+f(x)=then the discontinuity is known as infinite discontinuity.

Step by Step Solution

Step 1. Given information. 

A function has a removable discontinuity, a jump discontinuity, or an infinite discontinuity at x=c.

Step 2. removable discontinuity.

A function is discontinuous at x=c if its limits as role="math" localid="1648280454491" xc is not equal to the function value at x=c and this type of discontinuity is known as removable discontinuity.

limxcf(x)f(c)

Step 3. Jump discontinuity.

A function is discontinuous if its left limit and right limit are not equal and this type of discontinuity is known as jump discontinuity.

limxc-f(x)limxc+f(x)

Step 4. infinite discontinuity.

A function is discontinuous if its graph has vertical or horizontal asymptotes so that its left limit or right limit or both is equal to infinity.

limxc-f(x)= orlimxc+f(x)=
