Question

Given the parametric equations x = 2t and y = t−
t2/4
what are the x and
y coordinates at t = -2?

Answer 1

@Niguyver I think you will be surprised how easy this one is

Answer 2

you have the point (2t,t-t^2/4)
where 2t is the x-coordinate and t-t^2/4 is the y-coordinate for the value t

Answer 3

just enter in t=-2

Answer 4

is y , t-t^2/4 or (t-t^2)/4?

Answer 5

\[y=t-\frac{t^2}{4} \\ \text{ input } -2 \text{ for } t \\ y=-2-\frac{(-2)^2}{4}\]
I'm sure you can follow the order of operations

Answer 6

do the exponent part
then the division
then the subtraction
