State the domain and range of the following function.

{(6,-8), (9,3), (-3,5), (1,-6), (5,7)}
A.
Domain: {-3, 1, 5, 6, 3}; Range: {-8, -6, 6, 7, 9}
B.
Domain: {-3, 1, 5, 6, 3}; Range: {-8, -6, 5, 7, 9}
C.
Domain: {-8, -6, 3, 5, 7}; Range: {-3, 1, 5, 6, 9}
D.
Domain: {-3, 1, 5, 6, 9}; Range: {-8, -6, 3, 5, 7}

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

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

answer: -1
