STANDARDIZED TEST PRACTICE 12.) The model represents the equation x + 1 = 7.
Which is the first step in finding the value of x?
a.) Add counters to each side.
b) Subtract 7 counters from each side.
c.) Add 7 counters to each side.
d.) Subtract 4 counters from each side.

x+1=7 (x=6)  

Step-by-step explanation:

you add to the right side of the equation, and you get 6. hope this helps!

f(x) = log(x-4) - 3

The domain of log(x) is x>0 and we have log(x-4) so we have a domain of x>4, aka (4,∞).

The range of log is all real numbers, and so that will be the range of log(x-4) and log(x-4)-3.

Domain (4,∞);   Range (-∞,∞)
