f(x) = 4(x + 1)2 − 3
how can i write it when f(x) − 2

Your question is a bit confusing.

jhannybean · Answer

Is it $f(x) = 4(x+1)^2-3$  ?

anonymous · Answer

this is the original question 

Given the function f(x) = 4(x + 1)2 − 3, indicate the shifts that will affect the location of the vertex, and explain what effect they will have. Use complete sentences.

f(x−2) i know how to do this one 
f(x) − 2 i don't know how to do this one 
f(2x) i do know 
2•f(x) and i don't know 

i just want someone to teach me and ill explain everything

anonymous · Answer

yeah it is

jhannybean · Answer

Well, for the very last one, $$2(f(x)) = 2[4(x+1)^2-3]$$ I believe.

anonymous · Answer

okay thanks how about the second one?

jhannybean · Answer

It's simply taking a scaling factor of 2 and expanding your quadratic function accordingly

anonymous · Answer

like i know how to do it i just don''t know how it will be written in order for me to solve it

jhannybean · Answer

The second one implies youre shifting your graph down 2 units on the y-axis.

okay thanks i really do appreciate it
