Answer:
Step-by-step explanation:
<u>Inverse Function</u>
Let's call:
Divide by 2:
Assuming the base of the log is 10, apply exponential base 10:
Solving for x:
Swap variables:
Calling this function the inverse:
that seems right to me, I think. maybe something like that to double check
Answer:
{-5/4, 8}
Step-by-step explanation:
We are given (4u + 5)(8 - u) = 0. Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:
4u + 5 = 0 leads to u = -5/4, and
8 - u = 0 leads to u = 8.
The solutions are {-5/4, 8}
