1. **Which of the following equations represents the table below? Х 3 12 2 48 3 192 (a) f(x) = 4x + 3 (b) f(x) = 3x + 4 (c) f(x) = 3() (d)f(x) = 3(4) 2. **Explain how you came up with your answer to #1.

Respuesta :

Replace the values of x and check if you obtain the corresponding value of y:

f(x) = 3 (4^x)

x=0 , y=3

f(0) = 3 (4^0 ) = 3 (1) = 3

x=1 , y= 12

f(1) = 3 (4^1) = 3 (4) = 12

x=2 , y =48

f(2) = 3 (4^2) = 3 (16) = 48

x=3, y=192

f(3) = 3 (4^3) = 3 (64) = 192
