Which of the following functions is graphed below?

The closed dot indicates that an "equal to" in the comparison is required, and on the other dot it is open, so this requirement is not needed, so this equation is the answer

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!
