1)Consider the equation for the area of a rectangle with width 1 inch less than its length.

If x is the length, then the area y is given by

a) Y = x²(x - 1) b) Y = x (x - 1)

c) Y = (l) (w) d) Y = l (x - 1)

3)Determine if the following equation specify functions with independent variable x:

Y²- X² = 9, X IS A REAL NUMBER

a) Cannot be determined b) Specify a function

c) X is not a real number d) Does not specify a function
