Answer:

Absolute/extreme minimum at (-4,-2).

Step-by-step explanation:

Look at D. y=2(x+4)^2-2. Compare this to y = a(x-h)^2 + k. Through this comparison we see that h = -4 and k = -2.

Therefore, the vertex of the graph is at (-4,-2). The graph opens up. Therefore, (-4,-2) is the absolute minimum that y can have.

What is the area of the hexagon? 60 m 2 80 m 2 100 m 2 120 m 2

larisa86 [58]

We can think of this hexagon as two trapezoids with the same area. Each has height 5 and bases 6 and 10.

$A = 2 \left(\frac 1 2 (b_1 + b_2) h \right) = h(b_1 + b_2)$

$A = 5(6 + 10) = 80$

Answer: 80 square meters, second choice

Is (3,7), (3,8), (3,9), (3,10) a function

pogonyaev

Answer:

(3,7), (3,8), (3,9), (3,10) is not a function.

Step-by-step explanation:

A function is defined as a relation in which each input value has only a single output value.

This means that for each $x$ value there should be only one $y$

value. If this criteria is not fulfilled then the relation cannot be called a function.

For the given set of points, we notice that for $x=3$ , $y=7,8,9,10$ which shows there are many y-values o for a single x-value. This means there are many outputs for a single input. This disqualifies it to be a function.

Thus, (3,7), (3,8), (3,9), (3,10) is not a function.
