Answer:

Step-by-step explanation:

The negative out front only tells us which way the parabola will open. That means that the first one will open upside down, since it's got a negative out front. The value of the number that serves as the leading coefficient (the number stuck to the x-squared) determines how steep or wide-open the parabola's shape is. The leading coefficient in the first one is a 1, so it opens up exactly as wide as its parent graph does. The leading coefficient in the second one, a 2, means that the parabola will be skinnier or narrower than its parent. If the leading coefficient is greater than 1, the parabola will be narrower than its parent; if the leading coefficient is greater than 0 but less than 1, the parabola will open wider than its parent.

Which of the following describes the translation of the graph of y = x 2 to
VLD [36.1K]

Answer:

  reflect over the x-axis and shift down 3

Step-by-step explanation:

The leading coefficient of -1 means the graph is reflected over the x-axis. The addition of -3 to the function means each graphed point is shifted down 3 units from the original.

The graph of y = -x^2 -3 is the result of the transformation ...

Convert the following​
GrogVix [38]

Answer:

Step-by-step explanation:

a) 10 km to m

1 Km = 1000 m

10 km = 10 * 1000 = 10,000 m

b) 84 dag into dg

1 dag = 1000 dg

84 dag = 84 *1000 = 84,000 dg

c) 5.7 hg to cg

1 hg = 1000 cg

5.7 hg = 5.7 *1000 = 5700.0 = 5700 cg

d) 36.72 hm into m

1 hm = 100 m

36.72 hm = 36.72 *100 = 3672 m
