Answer:

-1

Step-by-step explanation:

This is a substitution question

The given equation is x+y+(-y)

And x is said to be-1,y=3

So let's solve

x+y+(-y)

Open the bracket first

x+y-y

So let's substitute

-1+3-3

-1+0

=-1

Therefore the final answer is-1

Which is an exponential decay function?
spayn [35]

Answer:

c)3/2(8/7)^x

Step-by-step explanation:

Evaluate the functions. 

1. Because 7/4 > 1 and the exponent is positive,

  the function does not decay.

2.Because 4/5 < 1 and the exponent is negative,

   the function does not decay.

3. Because 8/7 > 1 and the exponent is negative,

   the function decays.

4. Because 9/2 > 1 and the exponent is positive,

   the function does not decay.

A composite plot the functions verifies the answer.

If all the x's are exponents, then 3/2 (8/7)^-x is the only one that decays as x gets bigger.  That's because the base is greater than 1 and the x is negative.

please mark me brainliest :)
