Expansions and compressions are transformations that change the length or width of the graph of a function.


 To graph y = a*f (x)
 if a> 1, the graph of y = f (x) is expanded vertically by a factor a. 
 We have then:
 f (x) = 2/5 x ^ 2-2
 The function g (x) is a vertical stretch of f (x) by a factor of 2:
 g (x) = 2f (x)
 g (x) = 2 (2/5 x ^ 2-2)
 g (x) = 4/5 x ^ 2-4

 Answer:
 The equation of g (x) is: 
 g (x) = 4/5 x ^ 2-4

Answer:

  5.  C.  {(22, 10), (23, 10), (24, 7), (25, 5)}

  6.  C.  x = -2

Step-by-step explanation:

A relation is not a function if a vertical line intersects a graph of it in more than one place.

__

5. A set of ordered pairs is <u>not</u> a function if any of the first-values is repeated.

In set A, (22, ) is repeated.

In set B, (23, ) is repeated.

In set D, (24, ) is repeated.

In set C, no first-value is repeated, so the relation is a function.

__

6. The line x=-2 is a vertical line, so a vertical line intersect it in an infinite number of places. It is NOT a function.
