Answer:
f-1(x)=-
x-
Step-by-step explanation:
First, switch f(x) to the variable "y".
y=-
x-8
Next, swap "x" and "y" with each other.
x=-y-8
Next, lets move the denominator of 2 to the other side by multiplying both sides by 2. Your result will be...
2x=-3y-16
Now move -16 to the left side.
16+2x=-3y
To get "y" by itself, lets divide each side by -3. Our result is...
y=-x-
To finish the problem off, replace y with f-1(x) and your complete answer will be...
f-1(x)=-x-

Answer:
The table is a quadratic function
Step-by-step explanation:
Given
The attached table
Required
Tell if it is a quadratic function
The difference in the x values are uniform (i.e. difference of 1), so the following method can be applied.
(1) Subtract adjacent y values.
(2) Subtract adjacent differences in (1) above
Notice the calculated differences in (2) are the same.
<em>Hence, the table is a quadratic function</em>
