Find f ° g and g ° f , if they exist. f={(−4, −5), (0, 3), (1, 6)} and g={(6, 1), (−5, 0), (3, −4)} PLEASE HELP ME YALL

Step-by-step explanation:

hello,

fog(x)=f ( g(x) ) and gof(x) = g ( f(x) )

so

g(6)=1 so fog(6)=f(g(6))=f(1)=6

then

fog = {(6,6),(-5,3),(3,-5)}

gof = {(-4,0),(0,-4),(1,1)}

hope this helps

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
