The graph shows the population of black toads in a forest reserve since their introduction. It also includes functions drawn by different researchers to estimate the change in population of toads. Which function best models the researchers data

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

step-by-step explanation:

b and c

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

a is the best answer choice
