The function f(x) = x2 + 10x – 3 written in vertex form is f(x) = (x + 5)2 – 28. what are the coordinates of the vertex?

(–5, –28)
(–5, 28)
(5, –28)
(5, 28)

Option A is correct

(–5, –28)

Step-by-step explanation:

For a quadratic equation:

We know that convert of quadratic into vertex form, using the method of completing the square is,

where,

(h, k) is the vertex.

As per the statement:

The function

written in vertex form is:

From the above definition we have;

h = -5 and k = -28

Therefore,  the coordinates of the vertex is, (-5, -28)

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

40 i don’t know lololol
