a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
m∠x'z'y' = 90°
m∠mcy = 90°
bz' ≅ bz
zz' || yy'
step-by-step explanation:
given is the reflection of xyz across the line mn and reflected image is x'y'z'.
the shape and size of the image remains same as before. it means δxyz ≅ δx'y'z'
now, m∠x'z'y' = m∠xzy = 90° (using cpctc).
m∠mcy = 90° (because lines yy'⊥mn at point c).
xx' > yy' (clearly visible from the diagram).
bz' ≅ bz (rule of reflection: corresponding coordinates are equally distant across line of reflection mn).
zz'║yy' (because zz'⊥mn and yy'⊥mn).
xy ∦ x'y' (clearly visible from the diagram).
