Find the missing values for the exponential function represented by the table below.
Finger [1]

Answer:

x     y

-2   7

-1    10.5

0    15.75

1     23.625

2    35.4375

Step-by-step explanation:

The general equation of the exponential function is y=ab^x.

We know from our table that when x=0, y=15.75. Let's replace those values in our equation:

y=ab^x

15.75=ab^0

Remember that b^0=1, so:

15.75=a(1)

15.75=a

a=15.75

We also know from our table that when x=-1, y=10.5. Let's replace the values again:

y=ab^x

10.5=ab^{-1}

But we now know that a=15.75, so let's replace that value as well:

10.5=15.75b^{-1}

Remember that b^{-1}=\frac{1}{b}, so:

10.5=\frac{15.75}{b}

10.5b=15.75

b=\frac{15.75}{10.5}

b=1.5

Now, we can put it all together to complete our exponential function:

y=ab^x

y=15.75(1.5)^x

To find the missing values, we just need to evaluate our function at x=1 and x=2:

- For x=1

y=15.75(1.5)^x

y=15.75(1.5)^1

y=23.625

- For x=2

y=15.75(1.5)^x

y=15.75(1.5)^2

y=35.4375
