With these 2 !

1.what is the linear function equation represented by the graph?

2.function f is an exponential function. it predicts the value of a famous sculpture, in thousands of dollars, as a function of the number of years since it was last purchased.

what equation models this function?

Step-by-step explanation:

(1)Lets pick two points from the first graph

(0,1)  and (2,0)

The graph is linear so we use equation y=mx+b

where m is the slope and b is the y intercept

y intercept at (0,1)  so y intercept b = 1

now we find slope m using formula

m=-1/2  and b=1  so equation y=mx+b becomes

(2) Pick two point from graph (0,5) (1,7)

Since it is an exponential graph, we use y=ab^x

for (0,5) the equation becomes

for (1,7) the equation becomes

We know a= 5, so

The equation y=ab^x becomes

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
