Let the graph of g be a vertical shrink by a factor of 15 followed by a translation 8 units down of the graph of f(x)=x2. Write a rule for g.

Question

Let the graph of  be a vertical shrink by a factor of  followed by a translation 8 units down of the graph of . Write a rule for .

Answer 1

For the shrink factor of 15 need to multiply by 1/15

Translation down 8 subtract 8 so equation is

y=(1/15)x^2 -8
