If f(x) = x^2+3x-2, find f(-2)

f(-2)= -4

Step-by-step explanation:

f(-2) = (-2)² +3(-2) - 2

f(-2) = 4 - 6 - 2

f(-2) = -4

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

< 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
