Answer:

Step-by-step explanation:
We can find the inverse function of this excercise, isolating X and then changing the variables.


And now we change the variables and we get the inverse function:

Answer:
64
Step-by-step explanation:
First of all substitute the values to where ever you see their corresponding variables to make them multiply.
x = 9
y = 3
z = 2
so we get
8x as 8(9),
7z as 7(2)
2y as 2(3)
then the it's will be
8(9) - 7(2) + 2(3)
which is
72 - 14 + 6
finally we get
64
U would factor by grouping and get x^2(x-2) + 3(x-2) and then get (x^2 +3) (x-2)
