Let the function be represented by f(x).
Multiplying the number x by 4 results in 4x. Subtracting 2 from results give 4x - 2. So the function becomes:
f(x) = 4x - 2
Finding the inverse function:
Replace f(x) by y, and isolate x on one side of the equation and find the inverse:

Yes the inverse function represents the reverse process. Original function involved multiplication by 4 and then subtraction of 2. Inverse function involves addition of 2 and then division by 4. So the inverse represents the reverse of the given process.

Answer:
C. -8x + 10
Step-by-step explanation:
-2(3x + x - 5)
Combine like terms
= -2(4x - 5)
Distributive property
= -8x + 10
Answer:
For the second one would be 36°
