Since in each option, each input is mapped to only one output, all the options are correct.
<h3>When a relationship represents a function?</h3>
A relationship represents a function when each input is mapped to only one output.
In this problem:
- For the Venn sets, only one line departs each value of x, hence it is a function.
- For the ordered pairs, each value of x(2, 5 and -4), is mapped to only one value of y, hence it is a function.
- The graph has no vertically aligned points, hence it is a function.
Thus all the options are correct.

Answer:
∠D = 13°
Step-by-step explanation:
∠A and ∠D are vertical angles and thus are congruent, hence
x - 2 = - 3x + 58 ( add 3x to both sides )
4x - 2 = 58 ( add 2 to both sides )
4x = 60 ( divide both sides by 4 )
x = 15
∠D = x - 2 = 15 - 2 = 13°
I think so too it sounds right to me
Answer:
y = 2x - 5
Step-by-step explanation:
-5 because its the y-intercept where the line intercepts the y-axis
2x because it is your slope (the line jumps two units vertically every one unit horizontally)
Answer:
<u><em>h(x+2)= x² +5</em></u>
Step-by-step explanation:
h(x)= x² +5 -2x
h(x+2)= (x+2)² +5 - 2(x+2)
h(x+2)= x² +4x+4+5-4x-4
h(x+2)= x² +5
