Answer:

See attachment for graph

Step-by-step explanation:

Given

$y = x^2 - 3$

Required

The graph of the equation

First, we determine the range of y

$x = -3$

$y = x^2 - 3 \to y = (-3)^2 - 3 = 6$

$(-3,6)$

$x = -2$

$y = (-2)^2 - 3 = 1$

$(-2,1)$

$x = -1$

$y = (-1)^2 - 3 = -2$

$(-1,-2)$

$x=0$

$y = 0^2 - 3 = -3$

$(0,-3)$

$x = 1$

$y= 1^2 - 3 = -2$

$(1,-2)$

$x = 2$

$y =2^2 - 3 = 1$

$(2,1)$

$x = 3$

$y = 3^2 - 3 = 6$

$(3,6)$

1. 2x-y≤-6<br>2. 5x+4y ≥20<br>

expeople1 [14]

Answer

2x-y <or =-6

2x<or=-6+y

divide both sides by 2

x<or=1/2y+3

5(1/2y+3)+4y>or=20

5/2y+15+4y>or=20

5/2y+4y>or=20-15

13/2y>or=5

divide both sides by 2/13

y>or=10/13

2x-10/13<or=-6

2x<or=-6+10/13

2x<or=-68/13

divide both sides by 2

x< or =-34/13
