The function f(x)=x^2 -6x+3 is transformed such that g(x)=f(x-2). Find the vertex of g(x).

Lisa [10]

Answer:

$g(x) = (x-2)^2 -6(x-2) +3$

$g(x) = x^2 -4x +4 -6x +12 +3$

$g(x) = x^2 -10 x +19$

$g(x) = x^2 -10 x + 25 +19 -25$

$g(x) = (x-5)^2 -6$

$y= (x-h)^2 -kk$

Where h,k represent the vertex and we got:

$(h,k)= (5,6)$

(5,6)

Step-by-step explanation:

We have this original function given :

$f(x) = x^2 -6x +3$

And we want to find the vertex for this new function $g(x) = f(x-2)$ and we have:

$g(x) = (x-2)^2 -6(x-2) +3$

And solving the square we got:

$g(x) = x^2 -4x +4 -6x +12 +3$

And adding similar terms we got:

$g(x) = x^2 -10 x +19$

Now we can complete the square like this:

$g(x) = x^2 -10 x + 25 +19 -25$

$g(x) = (x-5)^2 -6$

The general equation is given by:

$y= (x-h)^2 -kk$

Where h,k represent the vertex and we got:

$(h,k)= (5,6)$

Ms . Rice needs to replace the 166.25 ft of edging on the flower beds in his back yard.The edging is sold in lengths of 19 ft ea

cricket20 [7]

Answer:

Ms. Rice need to purchase 9 lengths of edging.

Step-by-step explanation:

Length of edging Ms. Rice need to replace = 166.25 ft

Length of edging lengths sold = 19 ft

Total number of lengths of edging Ms. Rice needs to purchase = $\frac{length\ to\ be\ replaced}{edging\ lengths}= \frac{166.25}{19}= 8.75$

Since she would purchase whole lengths so it would rounded to 9 in number.

∴ Ms. Rice need to purchase 9 lengths of edging.
