Select the correct answer from each drop-down menu.
garry is cooking for his friends. he wants to buy some potatoes, which are priced at m dollars a pound. he has already spent b dollars on other
ingredients
the following expression represents the total amount of money that garry would spend after buying x pounds of potatoes
mi + b
if the amount already spent by garry on other ingredients, b dollars, is halved, then the value of m will
if the cost for each pound of potatoes, m dollars, is tripled, then the value of b will
will
and the value of mx

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
