The following is the graph of function g(x) if h = -4 and the parent function is f(x) = x2.

i understand where the -4 comes from, but the x^2 is confusing me.
Nnesha (nnesha):
x^2 is original graph of the quadratic equation (parent function )
Nnesha (nnesha):
|dw:1439741221254:dw|
like this
so they are saying -4 is shifting from the original graph(0)
Nnesha (nnesha):
vertex form
y=a(x-h)^2+k
k= vertical shift
h= horizontal shift

so is true
OpenStudy (anonymous):
using vertex form, you can always plug in numbers to check.

okay. thank you.
Nnesha (nnesha):
if k is positive you should shift the f(x) some units above the x-axis
if k is negative shift below the x-axis some units
for horizontal you would be careful abt signs
if h is negative shift the function some units to the Right side
if h is positive shift the function some units to the left side
Nnesha (nnesha):
\[y=a(x-(-4))^2+k\]
when negative by negative 4 :)
