1. In the function equation ff (xx ) = 1500 (1.43)^x, is this growth or decay? What is the percent of growth/decay? What is the initial value? 2. The number of bacteria in a sample can be modeled by the equation yy = 75(.8)^x, where y is the number of bacteria and x is the number of days elapsed. What is the rate of decay? 3. Monthly car sales for a certain type of car are $350,000 and sales are depreciating at a rate of 3% per month. a. Write an equation to represent this situation. b. What will the monthly sales be after 8 months? 4. Two auction websites start with 100 members each. At site A, the number of members doubles each month. At site B, 500 new members are added each month. Between months 5 and 6, which website gains more members and by how much?

horizontal translation of 2 units in the positive x direction

vertical translation of 3 units in the positive y direction

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
