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)

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
