F(x)=3(x-5)^2+6 how do you find the vertex of this function?

what is the vertex of this function?

Answers

Answer:

Vertex = (5, 6)

Step-by-step explanation:

f(x) = 3(x - 5)² + 6

First, the coefficient of x² is positive, therefore it has a minimum point.

To find the vertex,

we match the equation with the format (x - h)² + k.

The vertex is at ( h, k)

Vertex = (5, 6)

Hey there!!

Given amount of information:

  1. Saves $5 every week
  2. Get paid extra by $15 when he mows.

With this given information, we get to know that the number 15 is a constant and we don't know the number of weeks. Hence, it is a variable.

Let's take the number of weeks as 'w'

Let's now form a equation.

... 5w + 15 = ?

The total amount we want is $75. Hence,

... 5w + 15 = 75

... 5w + 15 - 15 = 75 - 15

... 5w = 60

... 5w/5 = 60/5

... w = 12

Hence, the number of weeks is 12.
