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

f(x)=2/3x-8, which give g(x) the greatest value.
