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

a. shift graph 2 units right

b. shift graph 2 units down

c. shift graph 2 units up

d. shift graph 2 units left

given the vertex,

y = a(x-2)^2 - 1

given the point,

1 = a(1-2)^2 - 1

1 = a - 1

a = 2

so,

y = 2(x-2)^2 - 1

y = 2x^2 - 8x + 7

g(x) = f(x+2), so

(D)
