(04.01) Which of the following best defines an input? (4 points)
O a
An input is the result of a relation or the function rule, usually the y-values in a set of ordered pairs or on a table or graph.
Ob
An input is a special type of relation for which there is a rule that pairs each input with exactly one output.
An input is a set of ordered pairs in which no y-value repeats.
Ос
Od

pairs or on a table or graph.

sorry not sure

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
