Find ∫c f*dr where f(x, y) = 〈 4xy3 , 6x2y2 〉 and c is a sequence of straight lines from (0,0) to (1,3) to (4,7) to (9,5) to (2,1

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.
