Answer:
-x² + 2x - 3
Step-by-step explanation:
Simply combine like terms together.
x² terms are added together
x terms are added together
Constants are added together
The statement is false, because -2 is larger than -3.
<h3>Is the statement true?</h3>
We know that -3 is a lower bound for the real zeros of f(x).
So, if we define k as the smallest real zero of f(x), we have:
-3 < k.
Then we can take, for example, k = -2.5
That is an allowed value for the real zero.
In that case, -2 is not a lower bound, because is false that:
-2 < k = -2.5
Then if -3 is a lower bound for the real zeros of f(x), we can't assume that -2 is also a lower bound (because -2 is larger than -3).

Answer:
$978
Step-by-step explanation:
Given:
- 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
