Question

The data below is from an exponential function. What is the value of the constant ratio?



-4
1/2
2
4

Answer 1

@hartnn can you help me?

Answer 2

y = a b^x
when x= 0, y=1
can you find 'a' from this ?

Answer 3

No, I am not really understanding. You saw the image right @hartnn?

Answer 4

I am thinking the answer is 8√3

Answer 5

Wait, so

1 = a b^0 ??

then wouldn't a = 1 because something times the 0 power is 0 right?

Answer 6

whats a constant ratio ?
what does it mean ?

Answer 7

ratio is a relation between two amounts, which shows how many times one contains the other, so constant ratio means that the value of ratio between two things is remaining constant with the passage of time.

Answer 8

ok, i guess its common ratio
the function will be
f = 2^x
so comparing with ar^(n-1), where 'r' is common ratio,
here, the common ratio will be 2

Answer 9

Oh, okay. That makes more sense. I think am going to go back and read my lesson plans again. I might have missed something. Thank you!

Answer 10

ok :)
welcome ^_^
