Question

cho ham so y = 2/3x. Dien so thich hop vaorong bang sau

Answer 1

Ta có bảng sau :

Answer 2

x	-0,5	-4/3	0	4,5	4/3
y	-1/3	-2	0	3	2

 

 

Answer 3

y = \(\frac{2}{3}x\)

Khi x = -0,5

=> y = \(\frac{2}{3}.\left(-0,5\right)=\frac{-1}{3}\)

Khi x = 4,5

=> y =\(\frac{2}{3}.4,5=3\)

Khi x = 6

=> y = \(\frac{2}{3}.6=4\)

y= \(\frac{2}{3}x\Rightarrow x=\frac{3}{2}y\)

Khi y = -2

=> x = \(\frac{3}{2}.\left(-2\right)=\left(-3\right)\)

Khi y = 0

=> x = \(\frac{3}{2}.0=0\)

Khi y =2

=> x = \(\frac{3}{2}.2=3\)

Answer 4

x	-0,5	-3	0	4,5	3	?
y	-1/3	-2	0	3	2	?
