The mapping shows a relationship between x and y. Which statement is true of the mapping?
A. y is not a function of x, since the y-value 3 corresponds to two different x-values.
B. y is a function of x, since the y-values do correspond to exactly one x-value.
C. y is not a function of x, since the x-values do not correspond to exactly one y-value.
D. y is a function of x, since the x-values do correspond to exactly one y-value.

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
