Sketch the graph of y = ( x + 3)^2 - 4 and identify the axis of symmetry.

Step-by-step explanation:

y=(x+3)²-4

or (x+3)²=y+4

its vertex is (-3,-4) and axis of symmetry is x+3=0 or x=-3

y=(x+3)²-4

when x=-5,y=0

x=-4,y=-3

x=-3,y=-4

x=-2,y=-3

x=-1,y=0

x=0,y=5

join the points (-5,0),(-4,-3),(-3,-4),(-2,-3),(-1,0),(0,5)

it is an upward formula with vertex (-3,-4)

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
