Question

From the graph of r, state each x-value at which f is dscontinuous. For each x-value, determine wether f argest) -value, determine whether f is continuous from the right, or from the let, or neither (Enter your answers from sm 4 -2 (smallest value) continuous from the right continuous from the left continuous from the right continuous from the left continuous from the right continucus from the left (largest value) continuous from the right continuous from the left MacBook Pro 5 6 8 command commandoption

Explanation / Answer

As is evident from the graph, points of discontinuity are:
x=-2; x=2; x=4;

At points of discontinuity, look for points with blue dots. These blue dots signify the function value at that point;

At x=-2, f(2-) = f(2) but it is not equal to f(2+); Thus x=-2, continuous from the left;

At x=2, f(2) = f(2+) but it is not equal to f(2-); Thus, x=2, continuous from the right;

At x=4,, f(4) = f(4+) but it is not equal to f(4-); Thus, x=4, continuous from the right;
