Which quadratic function is represented by the graph?
1 answer:
The equation of the quadratic function will be y = 5(x – 7)(x – 5). Then the correct option is B.
<h3>What is a quadratic equation?</h3>The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have
The quadratic function is represented by the graph.
Then the equation of the quadratic function will be
The graph is passing through (7, 0) and (5, 0). Then the equation of the function will be
y = a(x – 7)(x – 5)
Then the vertex of the graph is at (6, -5). Then we have
-5 = a(6 – 7)(6 – 5)
-5 = -a
a = 5
Then the equation will be
y = 5(x – 7)(x – 5)
Then the correct option is B.

A) At $3,300 for 600 seats, the average price per seat is 3300/600 = $5.50. The mix of tickets that results in that average can be found using an X diagram as shown below. The numbers on the right are the differences along the diagonals. When they are multiplied by 2, they add to 600. This shows that the required sales for revenue of $3,300 are
200 adult tickets
400 student tickets
b) When 3 student tickets are sold for each adult ticket, the average seat price is
(3*$4.50 +7.50)/4 = $5.25
Then the shortfall in revenue is ...
$3,300 -480*$5.25 = $780
