What are the coordinates of the vertex of the function f(x) = x2 − 12x + 5?

(6, 31)
(−6, 31)
(6, −31)
(−6, −31)

This means that the coordinates of the vertex of the function are

Step-by-step explanation:

To find the x-coordinate of the vertex of a quadratic function, we can use the formula:

We are given the function

In this function, and

Now we can input these values into our formula

This means that the x-value of the vertex is located at . To find the other half of the coordinate pair, we can now plug into the given function

This means that the coordinates of the vertex of the function are

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
