Answer:
y = 2x(x - 21)
Step-by-step explanation:
The given quadratic function y = -40x + 2x^2 - 2x
This can be rearranged as
y = 2x^2 - 2x - 40x
Here the Greatest Common Factor is 2x, we can take it out and write the remaining term in parenthesis.
y = 2x(x - 1 -20)
y = 2x(x - 21)
That's the answer.
Hope this will helpful.
Thank you.
Answer: Option C

Step-by-step explanation:
To solve this problem use the properties of the logarithms.
We know that the inverse function of
is
.
So when composing the function with its inverse function we have to:
.
Now apply this property on both sides of the equation

the answer is the option C
