given

x=t^2 and y=t-2

find a relationship between x amd y( express y in terms of x)

is the relationship a function

1. Reiny

solve each for t, then set these results equal to each other.

You will have an equation containing only x's and y's and constants. .

2. Shredder

X=t^2, y =t - 2, t =square røot of x. Y + 2 =t . Y + 2 =square root of x . But since u want it to be lyk dis ax +by = 2. . Y - square root of x = -2
