What is the range of that function?

The range is simply the set of possible outputs of a relation or function, which in this case is represented by the set of values in the oval on the right.

The input 1 maps to the output 2

The input 2 maps to the output 4

The input 3 maps to the output 9

The input 4 maps to the output 16

note: the domain would be {1,2,3,4} which is the set of input values shown in the oval on the left. It is the set of all possible inputs of a relation or function.

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.
