Question

PLEASE HELP!!
f(x)=-2(x-2)^2+4 (graph)

Answer 1

Can you tell me what each of the transformations are to get f(x)=x^2 to f(x)=-2(x-2)^2+4

Answer 2

-b/2a is the equation

Answer 3

That's not an answer to my question

Answer 4

for the general equation ax^2 + bx + c = 0
in vertex form f(x) = a(x-h)^2 + k
h = -b/2a and k = b^2/4a^2

transformations
-a means reflection across the x-axis
-h means moves the graph right
+ h moves the graph left
-k moves the graph down and
+ k moves the graph up

Answer 5

a means expand or shrink

Answer 6

to get f(x)=x^2 to f(x)=-2(x-2)^2+4
a = 2 twice as big ,
- =reflect across x-axis
x-2 = 2 places right
+4 = 4 places up
