By evaluating the piecewise function and the two side limits, the limit does not exist for the function at x = 2. (Correct choice: D)
<h3>What is the limit of a piecewise function at a given value of x?</h3>
Herein we have a piecewise function formed by three parts, two linear equations and a point. The limit of the function at a given value exists if the lateral limits and the function evaluated at that point brings out the same result.
By direct inspection, we find that the left limit of the function when x tends to 2 tends to 4, likewise with the right limit, but piecewise function is equal to 2 when we evaluate it at x = 2. Therefore, by evaluating the piecewise function and the two side limits, the limit does not exist for the function at x = 2. (Correct choice: D)

Answer:
-ab/1
Step-by-step explanation:
The multiplicative inverse of x/y is y/x, because when multiplied it equals 1.
x/y time y/x = xy/xy, which equals one.
In this case, -1/ab times -ab/1 = -1ab/-1ab, which equals one.
Answer:
A,D, and E are the answers on E2020
I think it’s B :) hope it helps
Answer:
A point will only map onto itself if it is on the line. Therefore (I am assuming the first point is (4, -4)) the answer is (4, -4).
