Consider the function consisting of all ordered pairs of real numbers (x, y) such that y = x3 [say "y is equal to x cubed"] The expression 'x3' is a shorthand notation for x  x  x Some ordered pairs that belong to this function are: (0, 0), (+1, +1), (1, 1), (+2, +8), (2, 8) This function is an example of a third degree function:
The function consisting of the set of all ordered pairs of real numbers (x, y) such that y = x4 [say "y is equal to x to the fourth"] is an example of a fourth degree function. The expression 'x4' is, of course, a shorthand notation for x  x  x  x Some ordered pairs that belong to this function are: (0, 0), (+1, +1), (1, +1), (+2, +16), (2, +16) You might find it interesting to draw a graph of this function.
