The graph will be a parabola opening upwards with a minimum value  when x = 0  and  f(x) will be = -7

so the range is  f(x) <= -7    or  (-∞, -7]

Idk how to do this without an image honestly
Art [367]

9514 1404 393

Answer:

  (x, y) ⇒ (x -m, y -n)

Step-by-step explanation:

Reverse the arrow and solve for the x and y on the left:

  (x +m, y +n) ⇒ (x, y)

This resolves to two relations:

  x + m ⇒ x

  x ⇒ x - m . . . . . subtract m

and

  y + n ⇒ y

  y ⇒ y - n . . . . . . subtract n

Putting these back together, we have ...

  (x, y) ⇒ (x -m, y -n) . . . . . maps P'Q' to PQ

_____

The original translation was right m and up n. The reverse translation is left m and down n. That is what the rule shows.

labwork [276]

Answer:

Booster club purchased 5 pies.

Step-by-step explanation:

Let the number of pies purchased by booster club be represented by n. The school also donated 3 pies to sell.

So that,

Total number of pies = n + 3

Given that there was 64 pieces of pies to sell after cutting each pie into 8 pieces.

Thus,

8( n + 3) = 64

8n + 24 = 64

8n = 64 - 24

8n = 40

Divide both sides by 8 to have,

n = 5

The number of pies purchased by booster club is 5.
