Question

Describe how the graph of y= x2 can be transformed to the graph of the given equation.

y = (x - 8)2 - 12

Shift the graph of y = x2 left 8 units and then down 12 units.

Shift the graph of y = x2 right 8 units and then up 12 units.

Shift the graph of y = x2 down 8 units and then left 12 units.

Shift the graph of y = x2 right 8 units and then down 12 units.

Answer 1

y = (x - 8)^2 - 12

is like:
y = (x-h)^2 + k
where h, and k represent the x and y value of the vertex of the parabola.

if h = 8, then what does k=?

Answer 2

k=12

Answer 3

@DemolisionWolf

Answer 4

pretty much, i'll just add the negative to it, so its y = -12

Answer 5

haha sorry, k=-12, not y

Answer 6

okay.

Answer 7

so it would be down by 12 correct?

Answer 8

so the value of k =-12 means the vertext is 12 down from the orgin.

Answer 9

and the h value of 8 means the vertex is 8 units to the right of the orgin

Answer 10

makes ense?

Answer 11

yes (: thank you

Answer 12
