Which expression represents the diagram where k= 1 A: k + k +5
B:k- 4
C: 2k + 3
D: k + 3

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

40 x 50 = 2000

step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
