B, D, A
A parametric function is a graph that uses a parameter, t, to set the values for x and y. i.e. x and y are functions of the parameter, t, instead of y being a function of x, etc.
Therefore;
y - 2 = t;
x = t^3
x = (y - 2)^3
x^1/3 - 2 = y
B
t is restricted to -3 <= t <= 5;
therefore, since x = t^3
(-3)^3 <= x <= 5^3
-27 <= x <= 125
D
Graph result is A.
t = -3, y = -5, x = -27;
t = 0, y = -2, x = 0;
t = 5, y = 3, x = 125;
To graph it on a graphing calculator (Some sort of TI-Model should do), select MODE. It should say
Norma | Sci | Eng
Float | 01234...
Radian | Degree
Func | Par | Pol | Seq
You want Par selected, instead of Function.
