Find the nonpermissible replacement for a in
this expression.
a + 6
a-8
Enter the correct answer.

8

Step-by-step explanation:

Assuming the given expresion is:

Then we have a rational expression with domain a≠8

This means that we can replace 'a' with all real values except a=8.

We obtain this by setting the denominator equal zero and solve for 'a'.

The reason is that, the expression is not defined when the denominator is zero.

Therefore the non-permisible replacement is 8

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
