The graph of the function f(x) = (x - 3)(x + 1) is shown. Which describes all of the values for which the graph is positive and decreasing?

all real values of x where x <-1
all real values of x where x < 1
all real values of x where 1 all real values of x where x>3

if you mean

then it's c. 8, -7/3

but if you mean

then it is

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

16 is the absolute value
