Me guysi need to know if the answer its correct or not . i choose b

, where,

Step-by-step explanation:

Domain of a graph is the set of all possible values of . It is the independent variable and is plotted along the axis.

From the graph,

The number of cars washed is along the axis. So, the domain includes the possible values for the number of cars washed.

The starting value of the graph is at point (0,-20) and the end point is (12,40)

So, the possible values of x varies from 0 to 12.

Therefore, the domain of the graph is:

, where,

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
