In the graph above, which of the following would most likely cause the line to shift from D1 to D2? A - An increase in consumer expectations

B - An increase in price

C - A decrease in consumer expectations

D - A decrease in price

A - An increase in consumer expectations

Step-by-step explanation:

Both the quantity and price increased, so the store most likely stocked more items and began charging more as a result of high demand.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
