Consider the following quadratic function. =gx+−2x2−16x25

(a)Write the equation in the form =gx+a−xh2k. Then give the vertex of its graph.
Writing in the form specified: gx=−4x+16
Vertex:, (4, 7)

(b) Graph the function. To do this, plot five points on the graph of the function: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function button.

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

step-by-step explanation:

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
