Answer:

Step-by-step explanation:

this is a really questuon so instead of x we put -3 so its going to look something like this. (PLUG IN -3 FOR X)

f(-3)= (-3)^2+6

f(-3)= -9+6 (-9 because of -3^2)

then the equation becomes

f(-3)= -9+6

(USING THE RULES) we get -3 as our Final answer

There were 800 farmers' markets initially in the USA in 2012. In 2013, the number of farmers' markets was 1.25 times the initial

zavuch27 [327]

For this case we have a function of the form:
$y = A * (b) ^ x
$
Where,
A: it is the initial amount
b: is the growth rate
x: is the number of years
Substituting values we have:
$y = 800 * (1.25) ^ x$
We have a growing exponential function because the value of b is greater than 1.
