If the domain of the square root function f(x) is x< or equal to 7, which statement must be true? a/ 7 is subtracted from the x-term inside the radical. b/ the radical is multiplied by a negative number. c/ 7 is added to the radical term. d/ the x-term inside the radical has a negative coefficient.

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!
