Is it a function and domain and range:

{(2,-4),(6,-2),(4,-2),(5,-4,(-8,-6) }

yes it is

for a relation to occur,

1. the domain must have unique images in the codomain

2. the whole domain must be mapped

when we look at the function above, we have

2-4

6-2

4-2

5-4

-8-6

Step-by-step explanation:

we see that all the domains are mapped uniquely to codomains

hence, it is a function, having a domain and range

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
