y = (-2) 2^(x+1)

Step-by-step explanation:

Whenever x increases from by 1, y decreases by doubling (the negative value), so the exponent is -2

When x = -1, y = -2.

So the exponential equation (NOT linear) is

y(x)   =  -2*2^(x+1)

Check:

y(-1) = -2*2^(-1+1) = -2*1 = -2

y(0) = -2*2^(1) = -2*2 = -4

...

y(2) = -2*2^(2+1) = -2*8 = -16

all good.

if x = 1, then the answer is 3.5

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
