How do I solve this? Th lesson doesn't explain it very well. What exponential function is the best fit for the data in the table?
x f(x)
1 -4
3 -1
4 3

f(x) = 4(3)x - 1 + 4
f(x) = 4(3)x - 1 - 4
f(x) = one fourth(3)x - 1 + 4
f(x) = one fourth(3)x - 1 - 4

How do I solve this? Th lesson doesn't explain it very well. What exponential function is the best fit for the data in the table?
x	f(x)
1	-4
3	-1
4	3

 f(x) = 4(3)x - 1 + 4
 f(x) = 4(3)x - 1 - 4
 f(x) = one fourth(3)x - 1 + 4
 f(x) = one fourth(3)x - 1 - 4

this is complicated lol but i suggest u to plug 1 for x in each equation and if u get -4 that should be the one :)

anonymous · Answer

The 4(3)x means $4\cdot 3^x$?

anonymous · Answer

the last one is $f(x) = \frac{1}{4}3^x - 1 - 4$?

anonymous · Answer

The last function is the one that better fits this set of points
