Question

Question 1

Eliminate the parameter.

x = square root of t, y = 4t + 1

y = 4square root of x + 1, x ≥ 0
y = 4square root of x - 1, x ≥ 0
y = 4x2 - 1
y = 4x2 + 1

Question 2

Eliminate the parameter.

x = t2 + 3, y = t2 - 2

y = x + 5, x ≥ 3
y = x2 - 5, x ≥ 3
y = x - 5, x ≥ 3
y = x2 + 5, x ≥ 3

Question 3

Eliminate the parameter.

x = 7t, y = t + 4

y = 7x + 4
y = 7x - 4
y = x divided by seven + 4
y = x divided by seven - 4
Question 4 (Essay)

Eliminate the parameter.

Answer 1

If I remember correctly since the last time I was on @satellite73 and @ganeshie8 were really good at Pre-Calc :)
