- y = amount of profit
- x = selling price of each widget
To find the maximum amount of profit, differentiate the equation, set it to zero and solve for x. Substitute found value of x into the original equation.
<u>Differentiate equation</u>
<u>Set differentiated equation to zero and solve for x</u>:
<u>Maximum profit</u>
Substitute x = 39 into the equation:
Therefore, max profit is $978
Answer:
The correct option is C.
Step-by-step explanation:
The function has axis of symmetry at , it represents that the parabola is along the x-axis and the standard form of parabola is
Where, a is scale factor and (h,k) is vertex.
The maximum or minimum value of a quadratic function is the vertex of parabola. So, vertex of parabola is (6,4).
The y-intercept of the function is (0,-32)
Therefore required equation of parabola is
Therefore option C is correct.
