Answer:
w = -4
Step-by-step explanation:
<u>Step 1: Distribute</u>
-2w - 14 = 2(w + 1)
-2w - 14 = 2w + 2
<u>Step 2: Add 2w to both sides</u>
-2w - 14 + 2w = 2w + 2 + 2w
-14 = 4w + 2
<u>Step 3: Subtract 2 from both sides</u>
-14 - 2 = 4w + 2 - 2
-16 = 4w
<u>Step 4: Divide both sides by 4</u>
-16 / 4 = 4w / 4
<em>-4 = w</em>

Answer:
f^-1(x) = 4+∛((x-6)/5)
Step-by-step explanation:
To find the inverse function, solve ...
x = f(y)
then write the answer in functional form.

The graph shows the function and its inverse to be reflections of each other in the line y=x, as they should be.
Answer:
A) 2
B) 3
C) -2
D) -1
Step-by-step explanation:
All you need to do is trace the given X value to the graph of the function after 'o' in (fog) or (gof). This is the same as finding the value of f(x) or g(x). After finding the value, make that value your x and trace to the new value on the other graph
a) Tracing -1 to y = f(X) gives y= 3. Tracing x =3 to g(x) gives 2
