Answer:
Yes
Step-by-step explanation:
Plug in the values for the variables that is given.
So the equation would be
5(-2)-3(2)-(-3)
Solve
5(-2)-3(2)-(-3)
-10-6+3
-16+3
-13
The answer is -13
To calculate<span> the </span>percentage<span> increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. If your answer is a negative number then this is a </span>percentage<span> decrease.</span>
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.
