The blue triangle has rotated from Quadrant I to Quadrant III about the origin . Describe the effects of the rotation on the coordinates of the blue triangle .

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!

you probably already have the answer but anyways it's b. 15.0
