A biologist determines that the path of a bee from its hive to its foraging site can be described by the parametric equations x= 4t-1 and y=2t^2+3t-4. Which of the following equations is the curve described by these parametric equations?

y=20x-9
y=20x+16
y=x^2+8x-25/8
y=x^2+4x-37/8

1. c'mon, guy -- you're not in Algebra I any more. Just plug in
t=(x+1)/4
and you have
y = 2((x+1)/4)^2+3(x+1)/4-4
Now just expand that out
