Which graph represents the function over the interval [-3, 3]?<br> floor-2
murzikaleks [220]

Answer:

In mathematics, the functions of the whole part are functions that take a real number and return a whole number, either by excess or by default.

 Function floor (or ground), that to each real number assigns the nearest whole number by defect, that is to say, the greater whole number equal or smaller than that real number.

 Let's evaluate the extremes of the interval

 x = -3

 g (-3) = floor (-3) -2 = -5

 x = 3

 g (3) = floor (3) -2 = 1

 Therefore, the graph that best corresponds to the function in the given interval is the attached graph.

HELP! 7th grade math! GIVE CORRECT ANSWER AND YOU WILL GET BRAINLIEST!!
blsea [12.9K]

Answer:

The lines are parallel

Step-by-step explanation:

x - y = 2

Solving for y

-y = -x+2

y = x -2

And the other equation is

y = x+1

These are both in slope intercept form

We notice that the slopes are both 1, but the y intercepts are different

That means the lines are parallel, but have different y intercepts
