Hello :
F(x)= x^2-4/2x^3-32x
F exist if : 2x^3-32x ≠ 0
2x^3-32x = 0
2x (x²-16)=0
2x(x-4)(x+4)=0
2x=0 or x-4=0 or x+4 =0
x=0 or x=4 or x= -4
the domain is : D= ] -∞ ; -4[ ∪ ] -4 ; 0[∪ ] 0 ; 4[ ∪ ]4 ; + ∞[

Why are halves a good choice for benchmark fractions for 1 1/3

Natalka [10]

Answer and explanation:

Benchmark fractions are fractions that are used as references in measuring other fractions. They are easily estimated and so can be used in measuring more "specific" fractions such as 1/5, 7/9, 3/7, 1/3 etc. If I wanted to measure 1 1/3cm for instance using a calibrated ruler, having centimeter measurements, I would first find 1cm on the ruler and then find half of one centimeter. Seeing that half is bigger than 1/3 but close, I could then estimate 1/3 to be somewhere less than 1/2 but a bit close to it
