Which set of ordered pairs does not represent a function? a.(0, 1), (2, 2), (4, 8), (-2, 7), (5, 8) b.(0, 1), (2, 2), (4, 8), (2, 7), (5, 8), (7, 9) eliminate , 6), (2, 7), (0, 5), (1, 5), (4, 9), (5, 4) , 2), (-3, 2), (-2, 2), (-1, 2), (0, 2), (1, 2)?

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
