There were 431 reserve seat tickets and 1356 general admission tickets sold.
What is Cost Function?
A cost function is a mathematical formula used to used to chart how production expenses will change at different output levels. In other words, it estimates the total cost of production given a specific quantity produced.
Let 'x' represent the number of reserve seats that were sold,
then '1787-x' represents the number of general admission tickets sold
we then have the following cost equation:
5792 = 4x + 3(1787-x)
solving for 'x' we have:
x = 431
1787-431 = 1356
Thus, there were 431 reserve seat tickets and 1356 general admission tickets sold.

x+y=1787 4x+3y=5792
Solve for x using substitution:
x=1787-y
Plug it into the other equation to find the value of y:
4(1787-y)+3y=5792
7148-4y+3y=5792
-y=-1356
y=1356
Now plug y back into any equation:
x+1356=1787
x=431
1356 general admission tickets were sold, and 431 reserved seats were sold.

The equation 4x² + 12x + 9 = 0 has exactly one solution. The correct answer would be an option (C).
What is a quadratic function?
The quadratic function is defined as a function containing the highest power of a variable is two.
The solutions to a quadratic equation are found using the quadratic formula, which is:
x = (-b ± √(b² - 4ac)) / 2a
As per option (C),
4x² + 12x + 9 = 0
Compare the given function to the standard quadratic function f(x) = ax² + b x + c.
We get a = 4, b = 12, and c = 9.
The discriminant of the equation,
b² - 4ac = (12)² - 4×4(9) = 144 - 144 = 0
Since the discriminant is zero, this means the equation has only one solution.
Therefore, the equation 4x² + 12x + 9 = 0 has exactly one solution.
Hence, the correct answer would be option (C).

quadratic formula: (-b(+or-)√(b^2-(4ac)))/2a.
You find that the equation 4x²+12x+9=0 only has the root of x=-1.5.
Since the solution is where the parabola crosses the x-axis, you can also figure out which equation has only one solution by whether or not the axis of symmetry lands is a solution or not. If the axis of symmetry is a solution, the function only has one solution (that being the vertex). If the axis of symmetry is not a solution, the function has to have either two or no roots. You can find the axis of symmetry by using the equation x=-b/2a. Using that equation you can find that the equation 4x²+12x+9 has the axis of symmetry being at x=-1.5 which means that the vertex is (-1.5,0). Since the equation 4x²+12x+9 has its vertex at (-1.5,0) and the vertex is the lowest or highest point of the function, that function only has one x-intercept meaning it only has 1 solution.
