Question

how is the graph of y = -8x^2 - 2 different from the graph of y = 8x^2?
a. it is shifted 2 units to the left.
b. it is shifted 2 units to the right.
c. it is shifted 2 units up.
d. it is shifted 2 units down

Answer 1

is there supposed to be a - in front of 8x^2 in the second function?

Answer 2

yes

Answer 3

okay so we have our two functions
y=-8x^2-2
and
y=-8x^2
notice the two functions would be the same if the -2 wasnt there in the first function

Answer 4

ok

Answer 5

just like in a linear equation the constant shows a vertical shift
so -2 is a vertical shift of ____ units down or up??

Answer 6

this should help:

Answer 7

down? @acxbox22

Answer 8

yes 2 units down :)
