What are the vertex and x-intercepts of the graph of the function given below?
y= x2 - 2x - 4

A. Vertex: (1, -49); x-intercepts: (8,0) and (-6,0)
B. Vertex: (0,0); x-intercepts: (-4,0) and (6,0)
C. Vertex: (-1, -21); x-intercepts: (6,0) and (4,0)
D. Vertex: (1,-40); x-intercepts: (6,0) and (7,0)

answer: this doesnt make any sense especially the photo.

step-by-step explanation:

1 1/5

step-by-step explanation:

(3x-8) or (3x+8)

step-by-step explanation:

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
