Which of the following function pairs are inverses?
irga5000 [103]

If the function f(x) = 5x – 3, then its inverse function g(x) will be (x + 3) / 5. Then the correct option is C.

<h3>What is inverse of a function?</h3>

Suppose that the given function is

f:X → Y

Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

 f⁻¹: Y → X

such that:

\forall \: x \in X : f(x) \in Y, \exists \: y \in  Y : f^{-1}(y) \in X

(and vice versa).

It simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'.

If the f(x) = 5x - 3, then the inverse function of the f(x) will be

g(x) = f⁻¹(x)

Then we have

5g(x) - 3 = x

5g(x) = x + 3

g(x) = (x + 3) / 5

Then the correct option is C.

Answer:

The chart A is correct

Pareto Chart

Step-by-step explanation:

Given chart is missing (Attached)

Find:

- Which chart represents the correct data.

- What other chart can be used to express the given data

Solution:

- Use the given values for each color and compare with the three charts A,B and C given.

                For Blue =    A (12)    ,    B(12)    ,    C(11)

                For Green = A(7)       ,    B(13)    ,    C(12)

- Hence,  The chart A is correct.

- Any other chart which can correctly express the information given should be a chart that uses bars or frequency to expresses the percentages. Pareto Chart expresses both bars and line chart(curve) to express the frequency of the data.
