Which represents a function ?

Second option

Step-by-step explanation: A function is a relation in which each x-coordinate corresponds to exactly one y-coordinate.

For the first table, this would not represent a function.

Notice that the -3 and the -3 correspond to different y-coordinates. In order for a relation to be a function, each x-coordinate must pair with one y-coordinate.

The second relation would be a function because notice that each x-term appears only once with a unique y-term so your answer would be the second one.

For the third table, the 0 gets paired up with two different y-values.

For the last relation, the x-term, -12, gets paired up with 4 and 24 which means that the relation can't be a function.

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
