When the function is given in vertex form y=a(x-h)2+k, how is the vertex found?

Given function is ...........(1)

We re write the function,

transfer k to LHS,

Since, One variable has degree 2 and one variable has degree 1.

⇒ Function Represent the equation of Parabola.

In given Function,

Coordinates of vertex is ( h , k )

So To, find the vertex of the function.

First we rewrite the function in vertex form that is like equation (1) then we compare them and write the coordinate of the vertex.

For Example,

1. y = 2(x - 2)² + 6 then vertex of the function is ( 2 , 6 )

2. y = -3 ( x + 3 )² - 6

    y = - 3 ( x - (-3) )² + ( -6) then vertex of the function is ( -3 , -6 )

a is the right answer

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
