which function is negative for the interval (–1, 1]?

⇒The Interval in which we have to find the function is Negative is (-1,1].

→(-1,1]=Semi closed or Semi Open Interval, Point -1, is not included in the set, but 1 is included in the set.

 ⇒ The meaning of negative here is,that either for positive or negative value of x , the value of f(x), that is y Should be negative.

⇒y is negative in third and fourth Quadrant.

Graph -(2), is the function , in which the function is negative for the interval (–1, 1].

29 is the correct answer

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
