erastovalidia [21]

It's basically 5,000*2=10,000
and 10,000/2=5,000. your answer would be either they multiplied 5,000 by 2 and 10,000 divided by 2, they increased the sales by 5,000

What is the value of h when the function is converted to vertex form?

elena-s [515]

Answer: h=7

Step-by-step explanation:

By definition the function in vertex form is:

$f(x)=a(x-h)^{2}+k$

Where (h,k) is the vertex of the parabola.

You must group the terms that contain the same variable in the function:

$f(x)=(x^{2}-14x)+29$

Complete the square as following:

$f(x)=(x^{2}-14x+49)+29-49$

Now you must rewrite it as following:

$f(x)=(x-7)^{2}-20$

Then:

h=7
