Question

What exponential function is the best fit for the data in the table?

x f(x)
3 10
4 16
5 28

A) f(x) = 3(2)^x − 2 + 4
B) f(x) = 3(2)^x − 2 − 4
C) f(x) = 1/3(2)^x − 2 + 4
D) f(x) = 1/3(2)^x − 2 − 4

Answer 1

I think it's A) f(x) = 3(2)x − 2 + 4?

Answer 2

Plug in your x values into the options of f(x), and see which one gives the corresponding value from the graph.

Answer 3

No, it is not A.

Answer 4

I don't know what it is then :(

Answer 5

Plug in the value of x given into the options, see which one gives f(x) = 10 ...when x= 3.

Answer 6

Is it D?
