Question

Given the function f(x) = 4(x + 1)2 − 3, indicate the shifts that will affect the location of the vertex and explain what effect they will have. use complete sentences ?

Answer 1

help?

Answer 2

@tukk u know anything ?

Answer 3

@nincompoop can u help?

Answer 4

absolutely
y = a(x-h)^2 + k
your vertex is (h,k)

Answer 5

(h, k) is used instead of (x, y)
but they are the same coordinate system

Answer 6

so what do i do?>

Answer 7

well if your k = -3
where will you find that in the graph?
3 points lower from zero correct?

Answer 8

zero being your level ground
-3 would be three-levels below zero

Answer 9

ok

Answer 10

so explain that

Answer 11

now let us look at the value of h

Answer 12

h = -1
is the same as x = -1 in the coordinate system
so your graph got pushed to the left side by a unit point from zero
