Question

What is the exponential function modeled by the following table?

Answer 1

x | f(x)
2 | 10
3 | 28
4 | 82

A)f(x) = 2x

B) f(x) = 2x + 1

C)f(x) = 3x

D)f(x) = 3x + 1

Answer 2

Just plug in x value in each choice and see which one gives you the corresponding f(x).

Also the x is exponent in all the choices.

Answer 3

Test each one out, but if you're good at mental math you can see that 3^x + 1 would make most sense by plugging in 2 for x you 9, then you add 9 + 1 = 10

Answer 4

Test each of the value's for x and see if its really that one, i only tried 2 for x

Answer 5

so it would be 3x + 1
