Let Elga = x
Alvin = 3x
They add to 72
x + 3x = 72
4x = 72, x = 18
Since Elga = x, we know Elga = 18

Solution: she is 18

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

Maslowich

Answer:

$g(x) = \frac{1}{9} \,x^2$ which agrees with option A in the list of possible answers

Step-by-step explanation:

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

$\frac{1}{9} \,f(x) = \frac{1}{9} \,x^2$

Therefore the answer to the problem is:

$g(x) = \frac{1}{9} \,x^2$
