Eliminate the parameter.
x = square root of t y = 3t + 7

Answer 1

ok... so if

\[x = \sqrt{t}\]

square both sides of the equation

\[x^2 = t\]

now substitute this into

y = 3t + 7

Answer 2

x = sqrt(t) implies t = x^2

so y = 3x^2 + 7.

Notice that x is non-negative, so you have only half of a parabola

Answer 3

Thanks everyone! That makes more sense!
