The following points are on the graph of a function:
Maurinko [17]

An inverse function reverses the roles of inputs and outputs (of x-values and y-values).  

If (2,4) is on the graph of a function, then (4,2) is on the graph of the inverse function.  

If (9,7) is on the graph of the inverse, then (7,9) would be on the graph of the original function.  

If (a,b) is on the graph of the function, then (b,a) is on the graph of the inverse.  

 

Getting to your question, which of the points listed has the inverse listed up in the table?

Could anyone help with this question?
Nikitich [7]

Answer:

I just answered this question, In case you missed it, here it goes again:

Values for the coefficient in the product k:

a=b=c=d=3*10^8, so the first four boxes should be filled with the number "3"

Drop down arrow: "does"

Step-by-step explanation:

We perform all the products of wavelength time frequency indicated for the column of the quantity "k":

a=1 * 10^{-10} * 3\, * 10^{18} = 3 * 10^{-10+18} = 3 * 10^{8}=

b=1 * 10^{-1}*3*10^9=3* 10^{-1+9}=3*10^8

c=600*10^{-6}*5*10^{11}=3000*10^{-6+11}=3000*10^5=3*10^3*10^5=\\=3*10^{3+5}=3*10^8

d=4*10^{-7}*7.5*10^{14}=30.0*10^{-7+14}=30*10^7=3*10*10^7=\\=3*10^{1+7}=3*10^8

Therefore, all products of these different wavelengths and their associated frequencies render the exact same answer : 3*10^8, which means that as one of these quantities increase, the other one will decrease in the same proportion to give the same numerical answer.

This means that the two quantities are associated via inverse proportionality. As seen in the equation below, if the quantities "x" and "y" are related by inverse proportionality (shown as one equals a constant "A" divided by the other variable), their product x*y will give that constant value "A" (which in our case is 3*10^8.

x=\frac{A}{y} \\x*y=A
