I have two questions, please help.
1. Determine the quadratic function f whose vertex is (2,1) and passes through (1,1).
f(x)=?
type in form f(x)=ax^2+bx+c
**pleasae show work**
2. Describe for the graph of g(x)=3square root x+2 can be obtained from the graph of f(x)=3square root x

(y+1) = k (x2)^2
2 = k(1)
k = 2
so
(y+1) = 2(x2)^2
y+1 = 2(x^2 4 x + 4) = 2 x^2 8 x + 8
y = 2 x^2  8 x + 7
