Find the properties of each Quadratic Function

Mathematics
1 answer:
Alla [95]3 years ago
7 0

Answer:

1.) up

2.) (-2,-5)

3.) x = -2

4.) (-2,-5)

5.) y = -5

6.) -∞ < x < ∞

7.) -5 < y < ∞

8.) (0,0)

9.) (0,0) and (-4,0)

10.) two solutions

Step-by-step explanation:

1.) because the parabola opens upward and the vertex is down

2.) the lowest point of the parabola is (-2,-5)

3.) If a line was drawn through the point x = -2, the two halves of the parabola would look symmetrical ( the same on both sides).

4.) The minimum point on the graph is ( -2,-5), because that is the lowest point on this upward parabola, and we can not determine the maximum.

5.) The minimum value of y is y = -5, because that is the lowest value of y on this graph, and we can not determine the maximum.

6.) Because the arms of the parabola continue traveling through negative infinity and positive infinity on the x-axis, the domain is -∞ < x < ∞.

7.) The arms of the parabola go from y = -5 to infinity, so the range of the parabola is -5 < y < ∞.

8.) The parabola first crosses the y-axis at the point (0,0)

9.) The parabola first crosses the x-axis at the points (0,0) and (-4,0)

10,) The solution to the parabola is the variable x. The solutions (x intercepts) of the parabola are x = 0 and x = -4.

Is 3+(−4) the same as −4+3? Explain. 3+(−4) the same as −4+3 because of the Property of Addition.
stiks02 [169]

Answer:  The − sign here means subtraction. However, recall that 4 − 7 can be rewritten as 4 + (−7), since subtracting a number is the same as adding its opposite.

Wants to build a regulation-size pool table that is 9 feet in length.The plans he ordered are 18 by 36 inches.what is the scale
Vlad [161]
<span>Length = the longer side

He wants to build a table with a length of 9ft.

The plans he has are 18ft x 36ft
Length of the plans =  36ft
Compare the length of the plans to the length he wants:
36 ft vs 9 ftThe length in the plans is 4 times longer than the length he wants.<span>

</span>Length he wants / Length of plans = your dilation scale factor

9 / 36 = ¼
1/4 = dilation scale factor

Hope this answers your question, and May the Force Be With You!

A vehicle at the starting line travels at a constant speed of 0.5 miles per min. which function could describe this vehicle.
Nutka1998 [239]
We have the equation y=mx+b. Here, m is multiplied by x and represents the slope in our line, or its speed. The b here represents the starting point. First, since we start at the starting line, b is 0 (since we start from 0). Next, since our speed is 0.5, we multiply x by 0.5 to get 0.5x=y
