Consider the infinite geometric series. In this image the lower limit of the summation notation is "n=1"
a. Write the first four terms
b. Does the series diverge or converge
c. If the series has a sum, find the sum

a) first term is -4. Multiply by ⅓ to get the next terms

-4, -4/3, -4/9, -4/27

b) Since

|⅓| < 1,

It converges

c) -4/(1 - ⅓)

= -4/⅔

= -4 × 3/2 = -6

sum = -6

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.
