Answer:

Option A

Step-by-step explanation:

The domain of a function is the set of all numbers that has an image in the co domain. It means that those elements are mapped to other elements and give output values.

From the figure we see that all the elements in $x$ are marked to other elements in $f(x)$ . So, the domain would be:

$\{-4, -1, 0, 2, 7\}$

Hence, Option A.

How many helmets must the company make and sell to break even? helmets

klio [65]

The sale the company must make and sell to break even is;

B=600

<h3>How many helmets must the company make and sell to break even?</h3>

Generally, the equation for the break even is mathematically given as

In conclusion

B=y vertex/price of each

Therefore

B=15600/26

B=600

In conclusion, the company's break even is

B=600

A company plans to sell bicycle helmets for $26 each. The company's business manager estimates that the cost, y, of making x helmets is a quadratic function with a y-intercept of 8,400 and a vertex of (500, 15,900). How many helmets must the company make and sell to break even?
