Step-by-step explanation:
Given that :
First 3 hours, rain fell at a constant rate of 25mmper hour
Next one hour, tmrain slowed down
Next 2 hours, rate of 20mm per hour
Piecewise function which models the situation :
{25t ; t in range {0, 3)
f(x){75 ; t in range {3,4}
{75 + 20(t-4) ; t in range {4,6}
Hence, the function.
