Question

How do you eliminate the parameter for this?


x = sqrt t , y = 3t + 7

Answer 1

ok

Answer 2

Square both sides of this equation: x = √t then substitute t to what it equal to.

Answer 3

And, ladies and gentlemen, this is how you eliminate this parameter.

Answer 4

@geerky42 so would it be y = 3 √x + 7, x ≥ 0

Answer 5

or does the squareroot cancel out completely?

Answer 6

t = √x ? I don't think so.

Answer 7

x = √t

x² = ( √t )²

x² = t

Answer 8

Is this clear? @serinaaa

Answer 9

@geerky42 y = 3x^2 + 7 ?

Answer 10

@geerky42 Thank you!!!!

Answer 11

No problem.
