Question

someone PLEASE HELP me I will reward a medal to who ever helps!!
Functions f(x) and g(x) are shown below:
f(x) = x^2
g(x) = x^2 − 8x + 16
In which direction and by how many units should f(x) be shifted to obtain g(x)?

Answer 1

First of all you have to factor g(x) try finding \[x_{1},x_{2}\]
and then use the following formula:
\[ax^{2}+bx+c=a(x-x_{1})(x-x_{2})\]

Answer 2

im sorry. how do I find \[x {1},x{2}\]

Answer 3

\[ax^{2}+bx+c=0\]
from the following formula:
\[x_{1,2}=\frac{ -b \pm \sqrt{D} }{ 2a }\]
where
\[D =b^{2}-4ac\]
