BRAINLIEST TO WHOEVER GIVES A GOOD EXPLANATION!! explain why x= -8 is not part of the domain of the function y= log 2 (x)

Original function:

f(x) = log2(x)

 Transformed function:

f(x) = -log2(x - 1) + 2

 The transformation process is to take  f(x)=log2(x)   and shift it to the right 1 unit and shift 2 units up.  Then flip it down.

A log cannot have a negative value for an argument.  Set the argument greater than zero.

x - 1 > 0

x > 1

 The domain is all values greater than 1.

To find the range, use the domain.

Evaluate f(1.00001), f(2) , f(200), and f(2000)

Then use those values to determine the range.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
