Answer:
0.4 since the number is non terminating and non repeating therefore it is irrational number.
-78 A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. The denominator in a rational number cannot be zero
15 The number 15 is a rational number. It is an integer and all integers are rational numbers.
0 Yes zero is a rational number. Thus, 0 can be written as, where a/b = 0, where a = 0 and b is any non-zero integer.
Answer with Step-by-step explanation:
We are given that a function
a.We have to find the inverse of m.
Suppose, 
Replace x by y and y by x
Substitute 
b.When the inverse function of given function is 
Then , we get fog(x)=
When f and g are inverse to each other then fog(x)=Identity function.
c.If f(x)=x
It is self inverse function.
Answer:
The correct answer is B
Step-by-step explanation:
Yes
Explanation replace both the x and y get the correct ans
