Answer:
![f(x) = (x-1)^2-6](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%28x-1%29%5E2-6)
Step-by-step explanation:
Rewrite the quadratic using the method of completing the square:
![x^2-2x-5=(x^2-2x+1)-1-5=(x-1)^2-6\\f(x) = (x-1)^2-6](https://tex.z-dn.net/?f=x%5E2-2x-5%3D%28x%5E2-2x%2B1%29-1-5%3D%28x-1%29%5E2-6%5C%5Cf%28x%29%20%3D%20%28x-1%29%5E2-6)
From this form it is immediately clear that the vertex of the parabola is at x=1 and its y-intercept at -6.

Answer:
Yes, the company can expect a profit in the long term
Step-by-step explanation:
In this question, we are to project if a company is expected to make a profit or loss given the information in the question.
Let’s use the scenario of 50 gadgets produced.
1 is expected to be faulty, while 49 is thus expected to work perfectly.
Now, on this 49 sold, there is an expectancy of $3 profit. Hence, this means that for a batch of 50 gadgets produced, the amount of expected profit will be 49 * 3 = $147
The amount that would be used to repair the faulty unit is $80. If we subtract this from the total expected profit, we have $147-$80 = $67
Hence, per 50 gadgets sold, a total of $67 in profit is to be expected
This means profit is expected in the long tey
