I've just begun to study Exponential functions: When you make a table starting with:

Question

-2 -4^x What are my coordinates?
-1
0
1
2

Answer 1

is your function y = -4^x ?

x = -2 , y = -4^-2 = -1/4^2 = -1/16
x = -1 , y = -4^-1 = -1/4
x = 0 , y = -1
x = 1 , y = -4^1 = -4
x = 2 , y = -4^2 = -16
