Jacques needs to convert the function f(x) = x2 − 6x + 14 to vertex form, f(x) = (x − h)2 + k, in order to find the minimum.
Anarel [89]

k = 5

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square

Since the coefficient of the x² term is 1 then

add/ subtract (half the coefficient of the x-term )² to x² - 6x

f(x) = x² + 2(- 3)x + 9 - 9 + 14 = (x - 3)² + 5 → k = 5

Karo-lina-s [1.5K]

Answer:

\frac{37}{42}

Step-by-step explanation:

Given :

\frac{92.5}{105}

Multiply numerator and denominator by 2 :

\frac{92.5}{105} \times\frac{2}{2}

\frac{185}{210}          [Divide both sides by 5 as it is a common factor]

\frac{185}{210} \div \frac{5}{5}

\frac{37}{42}
