Which statement is true about the function
Lana71 [14]
You solve for the domain by setting the radicand less than or equal to 0 and solving for x.  Dividing by a -x, we switch the sign so we have that the domain is less than or equal to 0, or all negative numbers.  We know that it breaks every law in math to have a negative radicand with an even index, so if the domain is all negative values of x, taking a negative of a negative gives us a positive.  The negative sign OUTSIDE the radical means you are flipping the graph upside down.  So instead of having a range of y is greater than or equal to 0 as does the parent graph, you have flipped it upside down so it heads more negative in regards to the range.  Therefore, the domain and the range both have the same sign, thee last choice from above.

The graph shows the amount of money paid when purchasing bags of peanuts at the zoo: What is the constant of proportionality? (4
jolli1 [7]

Answer:

The constant of proportionality is equal to 4

Step-by-step explanation:

The picture of the question in the attached figure

Let

y ----> the total cost in dollars

x ----> the number of bags of peanuts

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

To find out the constant of proportionality, we need to take one point from the graph

take the point (1,4)

Find the value of k

k=\frac{y}{x}

substitute the value of x and the value of y

k=\frac{4}{1}=\$4\ per bag
