Question

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


x f(x)
3 10
4 16
5 28


f(x) = 3(2)x − 2 + 4

f(x) = 3(2)x − 2 − 4

f(x) = one third(2)x − 2 + 4

f(x) = one third(2)x − 2 − 4

Answer 1

f(x) = 3(2)x − 2 + 4
is not an exponential function..
however
f(x) = 3(2)^x − 2 + 4
is..

Answer 2

Just input values of x and y and see if the equation holds true.
