Question

Let f(x)=25x2−2 .
The function g(x) is a vertical stretch of f(x) by a factor of 2.
What is the equation of g(x)?

Answer 1

For this case we have the following function:
 f (x) = 25x2-2
 Applying the transformation we have:
 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:
 g (x) = 2 * f (x)
 g (x) = 2 * (25x2-2)
 g (x) = 50x2 - 4
 Answer:
 The equation of g (x) is:
 g (x) = 50x2 - 4

Answer 2

Answer:

f(x)= 2/5x^2-2

g(x) = 4/5x^2-4
