Question

Y=4 times 1/2 to the power of x
i need help putting it into a table

Answer 1

Explanation:

y=4 times 1/2 to the power of x can be written symbolically as

4 4

y = 4(1/2)^x. This is the same as y = ------- or y = -------- * 2^(-x)

2^x 1

This function is a "decaying exponential."

A suitable table follows:

x 4(2^[-x]) x y

0 4(2^0) (0, 4)

1 4(2^1) (1, 8)

2 4(2^2) (2, 16)

and so on.
