For the equation F(x) = ax² + bx + c we have:
- maximum value if a<0
- minimum value if a>0
F(x) = -3x² + 18x + 3 ⇒ a = -3, b = 18
a < 0 ⇒ the function has a maximum value
Quadratic function has the maximum value (or minimum) at vertex of its parabola.
The maximum value is k at x=h where:
and k = F(h)

Therefore:
<h3>
The function has a maximum value of 30 at x = 3</h3>

Answer:</h2>
<u>The length is</u><u> 12 feet</u>
<h2>
Step-by-step explanation:</h2>
The width of the garden is 5 feet
After that the total edging is telling us the area
We know that
<h3>Area of rectangle = length x width</h3>
So
60 = length x 5
Length = 60 / 5
Length = 12 feet
