What the domain and range is for the function f(x) = x2 + 4x - 21.

prisoha [69]

Answer:

Step-by-step explanation:

Please use " ^ " to denote exponentiation: f(x) = x^2 + 4x - 21.

This function has a graph which is a parabola that opens up.

Its vertex is found by completing the square:

x² + 4x + 4 - 4 - 21, or

(x + 2)² - 25

Comparing this to the standard equation

(x - h)² + k, we see that h = -2 and k = -25.

Thus, the vertex (and the minimum of this function) is (-2, -25).

Thus, the range is [-25, ∞ ). This being a polynomial function, it has no restrictions on the domain: the domain is (-∞, ∞ )

I really need help ............!!!!!!

IrinaK [193]

Answer:

49 minutes

Step-by-step explanation:

To find the average time the machine was down per day, we need to add up the total time taken and then divide by the number of days. Since there are 5 days, we have:

$\frac{50 + 30 + 100 + 25 + 40}{5}$

$= \frac{245}{5}$

= 49

So, the average time per day is 49 minutes.

Hope this helped! :)

Compute the selling price of a sports drink that has a cost of $1.25 per item. The store needs to generate a profit of $0.50 per

luda_lava [24]

Answer:

The selling price would be $\$1.75$ .

Step-by-step explanation:

We have been given that a sports drink has a cost of $1.25.

We need to figure out the selling price of the sports drink so that the store is able to generate a profit of $0.50 per drink.

We know that profit is found by subtracting the cost of an item from selling price of the item. Therefore, selling price of the item can be found by adding the profit to the cost.

Therefore, the required selling price of the sports drink would be:

$\$1.25+\$0.50=\$1.75$
