Graph the relation. is the relation a function? why or why not? {(0,1), (3,5), (2,2), (-1,4)}

It is not a function because when you test it with the vertical line test the line intersect more than once. (If you need the graph, google "graph maker" and plot the points in)

Part A: y<4x-8 is a dotted line intercepting the y-axis at -8, and increasing by a value of 4, with shading bellow the line. The Second equation (which I can't fully type out) is a solid line intercepting the y-axis at 5,decreasing by a value of -5/2, and has shading above the line.

Part B: It does not because the point (5,-8) doesn't appear where the shaded areas meet.

Answer:

Step-by-step explanation:

1)a ) Let the constant proportionality =k

Direct proportion.So, y = kx

Plugin y = 6 and x =2 and find k

6 = k*2

6/2 = k

k = 3

Constant proportionality = 3

b) y = 3x

When x = 7 ; y = 3*7 = 21

y = 21

c)When x = 9,

y = 3*9

y = 27

d) When y = 9,

9 = 3*x

9/3 = x

x = 3

e)when y = 30

30 = 3*x

30/3 =x

x = 10

3) y is inversely proportion to x³

$y =k\dfrac{1}{x^{3}}\\\\3 =k *\dfrac{1}{2^{3}}\\\\3=k*\dfrac{1}{8}\\\\3*8=k\\\\24 = k$

b) when x = 4

$y=24*\dfrac{1}{4*4*4}\\\\y=\dfrac{3}{8}$

c) When x = 6

$y = 24*\dfrac{1}{6*6*6}\\\\y=\dfrac{1}{9}$

d) When y = 24

$24= 24*\dfrac{1}{x^{3}}\\\\x^{3}*24=24\\\\x^{3}=\dfrac{24}{24}\\\\x^{3}=1\\\\x = 1$
