20 POINTS BRAINLIEST FOR CORRECT ANSWER !! PLEASE HELP Describe the similarities and differences between the graphs of the functions in items 8 and 9. How are these similarities and differences indicated by the functions themselves?

Item 8: y=x^2-3x-4
Item 9: y=-x^2+3x+4

Step-by-step explanation:

similarities:

both items (equations) have the same roots: (-1,0) and (4,0),

both items are in quadratic form

differences:

both have different y-intercepts:

item 8: (0,-4)

item 9: (0,4)

both have a relative min/max at x=1.5

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
