F: R → R is given by, f(x) = [x]
It is seen that f(1.2) = [1.2] = 1, f(1.9) = [1.9] = 1
So, f(1.2) = f(1.9), but 1.2 ≠ 1.9
f is not one-one
Now, consider 0.7 ε R
It is known that f(x) = [x] is always an integer. Thus, there does not exist any element x ε R such that f(x) = 0.7
So, f is not onto
Hence, the greatest integer function is neither one-one nor onto.
The answer was quite complicated but I hope it will help you.
Answer
both get the same equation 10x=1000 which simplifies to x=100. HOPE THIS HELPED!!!
Step-by-step explanation:
Do I really need to?
Answer:
30
Step-by-step explanation:
20% = 20/100= 1/5
It is 1/5 of the number 150
Taking the problem what is 20% of 150
Is means equals and of means multiply
what is 20% of 150
W = 20% * 150
Change 20% to a decimal
W = .20 * 150
W = 30
All of the positive and negative numbers are integers.
Answer:
70 degrees
