Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x? f(x) = (x – 1)2 + 3 f(x) = (x – 1)2 + 5 f(x) = (x + 1)2 + 3 f(x) = (x + 1)2 + 5

 First Option

Step-by-step explanation:

Quadratic quadratic functions have the following form:

Where the point (h, k) is the vertex of the function.

For a quadratic function of the form the vertex of the function is at the point

In this case the function is:

Then:

The vertex is:

Note that

Therefore the vertex is the point

Finally we have that

The function in vertex form is :

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
