Which graph represents the function on the interval [-3 , 3] ?<br><br> f(x)= [x]-3
seropon [69]

Answer:

the graph that best corresponds to the function in the given interval is the  down left graph.

Step-by-step explanation:

Given : f(x)= [x]-3 and graph .

To find  : Which graph represents the function on the interval [-3 , 3] ?

Solution :  Let's evaluate the extremes of the interval in given function f(x).

X= -3,             f( -3 )= [ -3 ] - 3 .

                      f( -3 ) = -6 .

X= 3,          f( 3 )= [ 3 ] - 3 .

                      f( 3 ) = 0.

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

Triangle M R N. Angle N is 98 degrees. Side N M extends to form exterior angle with a measure of 109 degrees.
Scilla [17]

Answer:

16 degrees

Step-by-step explanation:

<u><em>The question is</em></u>

Find the measure of angle R

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles

so

In this problem

m\angle N+m\angle R=109^o

we have

m\angle N=93^o

substitute

93^o+m\angle R=109^o

m\angle R=109^o-93^o=16^o
