Answer:
Question 1)
The graph of [tex]y=\dfrac{2}{x}[/tex] is attached to the answer.
The graph of such a functio lies in first and third quandrant such that the graph tends to 0 when x→∞ or when x→-∞ and graph tends to ∞ when x→0.
We can also show the values of this equation on a table:
x-values y-values
1/2 4
1 2
2 1
3 2/3
Question 2)
The graph of the equation [tex]y=x^{2}+2x-3[/tex] is attached to the answer.
we will get a upward parabola with this equation whose vetex is: (-1,-4).
The ordered pair on the graph could be shown with the help of a table:
x-values y-values
-1 -4
0 -3
-3 0
1 0
