PLEASE HELP ME WITH THIS MATH QUESTION

a

Step-by-step explanation:

The range is the range of y values covering the graph.

The graph has its lowest value at y = - 4 and its upper value at y = 4

However, the open circles at either end of the curve indicate that y ≠ - 4 or 4

Thus

range is {y | - 4 < y < 4 , y ∈ R }

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
