ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions.

i am very sure that the answer is D which is domain does not change and the range changes.

Step-by-step explanation:

it is because always range value can varry more over when H(x) is equal to A and range is equal to B .

A=B

similarly

A= -B

b. astronomers

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
