3. The graph of part of linear function h is shown on the grid. (a) Write an inequality to represent the domain of the part shown. Explain your answer.
(b) Write an inequality to represent the range of the part shown. Explain your answer.

Let's define the notation used

A white dot means that the point does not belong to the set, here we use the symbol ( and ) (or > and <)

A black dot means that the point does belong to the set, so here we use the symbols [ ] (or ≤ and ≥)

An arrow means that the set continues infinitely.

a) Domain.

The domain is the set of the possible values for the input, x.

We can see that the smaller value in the domain coincides with x = 4, where we can see a white dot.

And at the end, we can see an arrow, so the domain continues to infinite.

Then the domain is:

D: 4 < x.

b) Range.

The range is the set of the possible values of y.

We can see that the maximum value of y is y = -2, whit a white dot.

And then we can see an arrow that points downwards, so the possible values of y extend in all the negative range.

Then we can define the range as:

R:  y < -2

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
