          The retail flat rate in dollars for first-class mail weighing up to 5 ounces could be computed by the piecewise-constant function P, where x is the number of ounces.

P(x) = 
0.90 if x < 1
1.14 if 1 < x < 2
1.38 if 2 < x < 3
1.62 if 3 < x < 4
1.86 if 4 < x < 5

Evaluate P(3.9) and P(3). Sketch the graph of P. What is the domain of P? Where is it discontinuous on its domain?

(a) P(3.9) =
(Type an integer or decimal)

Step 1

9) and P(3) using the given piecewise function. For P(3.9), since 3 < 3.9 < 4, we use the function 1.62 if 3 < x < 4. So, P(3.9) = 1.62. For P(3), since 2 < 3 < 3, we use the function 1.38 if 2 < x < 3. So, P(3) = 1.38. Now, let's sketch the graph of P. The Show more…
