A sequence of transformations maps ABC onto ABC. The type of transformation that maps ABC onto ABC is a [blank] When ABC is refleted across the line x=-2 to form ABC, vertex [blank] of ABC will have the same coordinates as B.

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
