Chapter 4.3, Problem 59E

Finding Values In Exercises 59-62, find possible values of a and b that make the statement true. If possible, use a graph to support your answer. (There may be more than one correct answer.)

${\displaystyle {\int }_{-2}^{1}f\left(x\right)dx+{\displaystyle {\int }_1^{5}f\left(x\right)dx={\displaystyle {\int }_a^{b}f\left(x\right)dx}}}$
