When using bits to represent fractions of a number, can you create all possible fractions?.

Every rational number has a base-2 representation, but only the ones with denominators that are powers of 2 will require a finite number of bits to fully represent it.

For example,

\dfrac12 = 1\cdot2^{-1} = 0.1_2

\dfrac14 = 1\cdot2^{-2} = 0.01_2

\dfrac34 = \dfrac12 + \dfrac14 = 0.11_2

\dfrac{1023}{1024} = 1 - \dfrac1{2^{10}} = 1_2 - 0.0000000001_2 = 0.1111111111_2

whereas a number whose denominator contains anything else like 1/3 will need an infinite number of bits to represent it exactly.

\dfrac13 = \dfrac1{2^2} + \dfrac1{12} = \dfrac1{2^2} + \dfrac1{2^4} + \dfrac1{48} = \dfrac1{2^2} + \dfrac1{2^4} + \dfrac1{2^8} + \dfrac1{192}

and so on, so that it has a repeating but non-terminating base-2 representation

\dfrac13 = 0.010101\ldots_2

Q3) f(x) 2x^2 - 5x, g(x) = 3x^3 find g(4x)
mrs_skeptik [129]

Answer:

g(4x) = 192x^3

Step-by-step explanation:

For this problem, f(x) is irrelevant since we are simply are dealing with g(x).  We will simply replace the value of x in g(x) with 4x.  So let's do that.

g(x) = 3x^3

g(4x) = 3(4x)^3

g(4x) = 3(4^3)(x^3)

g(4x) = 3(64)(x^3)

g(4x) = 192x^3

Hence, g(4x) is 192x^3.

Cheers.
