Question #eabbb

Answer 1

`y=12x^2toA`

Explanation:

`"Initially we have " ypropx^2`

`rArry=kx^2" where k is the constant of variation"`

To find k substitute the condition that y = 48 when x = 2

`y=kx^2rArrk=y/x^2=48/4=12`

`rArr" equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=12x^2)color(white)(2/2)|)))toA`
