We have

a.  `f(x)=x^2`

`x= 0,+-1,+-2,+-3`

`y=0,+1,+4,+9`

`Here`

`x=0 then y=0, x=+-1, then y=1, `

`x=+-2 then y=4 ``and x=+-3 then y=9`

b.`g(x)=2x^2`

`x=0,+-1,+-2,+-3`

`y=0,+2,+8,+18`

c. `h(x)=(1/4)x^2`

`x=0,+-1,+-2,+-3`

`y=0,(1/4),+(1/4)xx4,+(1/4)xx9`

`y=0,+1/4,+1,+9/4`

`A)`                `f(x)= x^2`          `x|0 | +-1|+-2|+-3|`

                                                `y|0| +1 |+ 4| +9|`

 

`B)`              `g(x)=-2x^2`       `x|0|+-1|+-2|+-3|`  ``  ``  

                                                 `` `` `y|0| +2 |+ 8| +18|`

 

`C)`         `h(x)= 1/4 x^2`             `x|0|+-1|+-2|+-3|`  

                                                 `y|0|+1/4|+1|+9/4|`
