What is the vertex form of y=-2x2+4x + 3?

sukhopar [10]

Answer:

$y=-2(x-1)^2+5$

Step-by-step explanation:

we have

$y=-2x^2+4x+3$

This is the equation of a vertical parabola open downward

The vertex represent a maximum

Convert the quadratic equation into vertex form

step 1

Factor -2

$y=-2(x^2-2x)+3$

step 2

Complete the square

$y=-2(x^2-2x+1)+3+2$

$y=-2(x^2-2x+1)+5$

step 3

Rewrite as perfect squares

$y=-2(x-1)^2+5$ ----> equation in vertex form

The vertex is the point (1,5)

Graph the feasibility region represented by the given inequalities and find the maximum profit if P = 4x + 5y. x ≥ 5 y ≤ 10 2x -

Brilliant_brown [7]

First, graph the three inequalities: x ≥ 5 , y ≤ 10 , 2x - y ≤ 8

Next, look for the 3 intersections (vertices) of the lines: (5, 2) , (5, 10) , (9, 10)

Finally, input the vertex coordinates into P = 4x + 5y and look for the biggest #.

(5, 2): 4(5) + 5(2) = 20 + 10 = 30

(5, 10): 4(5) + 5(10) = 20 + 50 = 70

(9, 10): 4(9) + 5(10) = 36 + 50 = 86

Answer: maximum profit = 86
