A function and its inverse are shown on the graph. Which statement describes the relationship between the function and its inver

WARRIOR [948]

Answer:

Option (B)

Step-by-step explanation:

Domain of function is defined by the set of x-values (input values) and Range of a function is a set of y-values (output values).

From the graph attached,

Domain of f(x) → Set of all real numbers

Range of f(x) → y-values > 0

Domain of $f^{-1}(x)$ → Set of all real numbers

Range of $f^{-1}(x)$ → y < 2

Therefore, domain of both the functions is a set of all real numbers.

Option (B) is the correct option.

inn [45]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Mean (m) = 266 days

Standard deviation (s) = 16 days

A.) p(( Z ≤ (x - m) /s) = 2.5%

p(( Z ≤ (x - 266) /16) = 0.025

(x - 266) /16 = - 1.96 (Z probability calculator)

x - 266 = - 31.36

x = - 31.36 + 266

x = 234.64

B.)

p(( Z ≤ (x - m) /s) = 2.5%

p(( Z ≤ (x - 266) /16) = 0.025

(x - 266) /16 = - 1.96 (Z probability calculator)

x - 266 = - 31.36

x = - 31.36 + 266

x = 234.64

p(( Z ≤ (x - m) /s) = 2.5%

p(( Z ≤ (x - 266) /16) = 0.025

(x - 266) /16 = 1.96 (Z probability calculator)

x - 266 = 31.36

x = 31.36 + 266

x = 297.36

Hence,

234.64 < x <297.36

C.)

p(( Z ≤ (x - m) /s) = 2.5%

p(( Z ≤ (x - 266) /16) = 0.025

(x - 266) /16 = 1.96 (Z probability calculator)

x - 266 = 31.36

x = 31.36 + 266

x = 297.36
