Determine whether the relation (7,4), (5.-1), (3, -8), (1, -5), (3,6) is a function. Explain.

No it is not a function

Step-by-step explanation:

it is not because of the sets of data (3,-8) and (3,6). as you can see the x values are the same( 3 is the x value in each set) and the y vaues (-8 and 6) are different.

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.
