Question

Eliminate the parameter.

x = t + 4, y = t^2

Answer 1

we can 'eliminate' the parameter t

by algebra
x -4 = t

now substitute into y

Answer 2

So it becomes x = -4 + 4 and y = -4^2? @perl

Answer 3

The answers are:
y = √x + x + 4
y = √x - 4
y = x^2 + 16
y = x^2 - 8x + 16

I chose y = x^2 + 16 as the answer. Is that right? @AnswerMyQuestions @perl @iGreen

Answer 4

@brainbuzzed5646 @TheSmartOne @rose18920 any help?

Answer 5

sorry @sunshine201 math is not my best subject.... i don't want to give you a wrong answer but if no one else answers you back you should just go with your own answer :)

Answer 6

Okay :) thank you anyway.

Answer 7

we can 'eliminate' the parameter t

by algebra first solve for t
x -4 = t
now substitute into y = t^2

y = (x-4)^2

Answer 8

now you can expand that

Answer 9

So the answer would be y = x^2 - 8x + 16?
