Question

If f(x) = x ^ 2 is vertically compressed by a factor of 9 to g(x) , what is the equation of g(x) ?

Answer 1

`g(x) = (1)/(9) \,x^2` which agrees with option A in the list of possible answers

Explanation:

A vertical compression by a factor 9 is represented by the transformation:

`(1)/(9) \,f(x) = (1)/(9) \,x^2`

Therefore the answer to the problem is:

`g(x) = (1)/(9) \,x^2`
