Every transformation like

f(x)\mapsto f(x)+k

translated the graph vertically, k units up if k is positive, k units down if k is negative.

So, in your case, we have that -x^2-1 is the same graph as -x^2, except it's shifted 1 unit down.

The volume of dry goods like apple or peaches can be measured using bushels, pecks and quarts. A bushel contains 4 pecks and a p
Lisa [10]

Answer: q= 32b

Step-by-step explanation:

Given:  A bushel contains 4 pecks and a peck contains 8 quarts.

i.e.  A bush = 4 pecks

A peck = 8 quarts

Then, Number of quarts in 1 bush = 4 (8) =32

Let b = number of bushes and q = number of  quarts

Number of quarts(q) in b bushes = 32b

hence, required equation:q= 32b which describes the relationship between the number of b bushels and the number of q quarts.

Give the domain and range of the relation.
Alex_Xolod [135]

Answer:

Please check the explanation.

Step-by-step explanation:

Finding Domain:

We know that the domain of a function is the set of input or argument values for which the function is real and defined.

From the given graph, it is clear that the starting x-value of the line is x=-2, the closed circle at the starting value of x= -2 means the x-value x=-2 is included.

And the line ends at the x-value x=1 with a closed circle, meaning the ending value of x=1 is also included.

Thus, the domain is:

D: {-2, -1, 0, 1}       or    D: −2 ≤ x ≤ 1

Finding Range:

We also know that the range of a function is the set of values of the dependent variable for which a function is defined

From the given graph, it is clear that the starting y-value of the line is y=0, the closed circle at the starting value of y = 0 means the y-value y=0 is included.

And the line ends at the y-value y=2 with a closed circle, meaning the ending value of y=2 is also included.

Thus, the range is:

R: {0, 1, 2}   or    R: 0 ≤ y ≤ 2

A plumber has a 2-meter length of pipe. He needs to cut it into sections that are 10 centimeters long. How many sections will he
musickatia [10]

Answer:

  20

Step-by-step explanation:

For cutting problems, we make the assumption that there is no loss of length due to the material moved or removed by cutting.

  2 m = 200 cm

so there are ...

  (200 cm)/(10 cm/section) = 20 sections

that can be cut from the pipe.
