Given the following table, write the equation to represent the exponential function.

x y

-1 -4

0 -2

1 -1

2 -0.5

  y = -2·(1/2)^x

Step-by-step explanation:

The ratio of one table entry to the one before is ...

  (-2)/(-4) = 1/2

so this is the growth factor.

The multiplier is the value of y when x=0, which is -2. So, the equation is ...

  y = (multiplier)·(growth factor)^x

  y = -2·(1/2)^x

This can also be written using a negative exponent:

  y = -2·2^(-x)

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

miss u!
