Prove that the Greatest Integer Function f: R -> R given by f(x) = [x], is neither one-once nor onto, where [x] denotes the g
Karo-lina-s [1.5K]
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.

Find the area of the parallelogram, trapezoid, rhombus, or kite. Round to the nearest tenth, if necessary.
Sergeeva-Olga [200]

Answer:

  • 69.3 yd²

Step-by-step explanation:

Area equation of the parallelogram

  • A = bh, where b- base, h - height

Looking at the picture, we can see the right triangle is isosceles as one of interior angles is 45°. It has hypotenuse of 7 and legs of h.

As per property of 45° right triangle the hypotenuse is √2 times the leg.

It gives us

  • h√2 = 7 ⇒ h = 7/√2 = 4.95 (rounded)

Now find the area

  • A = 14*4.95 = 69.3 yd²
