For which interval is the average rate of change of f(x) negative?
from x = -3.5 to x = -1
from x = -3 to x = 3
from x = 0 to x =2.5
from x = 3 to x = 4.5

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

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

do you have a picture of the table

b and c
