Expert Answer

Step 1

From the given graph it is observed that, the function is continuous piecewise function.

The function defined on the interval [-7,-5]U[-5,-3]U[-3,1][1,2] [2,5] Definition used: "If f(b) f(a) for all b >a where a.be I then the function f(x) is said to be strictly increasing on the interval P"

Step 2

Consider the interval [–7, –5].

From the graph, it is observed that f(–7) = 1 and f(–5) = –2.

Note that, f(–5) < f(–7) for –5 > –7.

Thus, the function is not increasing on the interval [–7, –5].

Step 3

Consider the interval [–5, –3].

From the graph, it is observed that f(–5) = –2 and f(–3) = 2.

Note that, f(–3) >  f...
