Question

g(x) = x2 + 3, what is the change made to g(x) if the parent function is f(x) = x2?

Yeah totally stumped here.

Answer 1

this isn't as hard as you think...

Answer 2

Im over thinking it.. i know :/

Answer 3

if I have a function f(x) = x^2,

and you want to make me have a function that is "x^2 + 3"

what do you need to do to my function?

Answer 4

im looking haha

Answer 5

they are practically the same, right? but you wish mine had a "plus 3" on the end... so that's it...

g(x) = f(x) + 3

because f(x) is just x^2

So g(x) = x^2 + 3

Answer 6

Try graphing the functions and you will probably see the change.
Or try making a t-table with both functions and see if you can see what change is the result.

Answer 7

so would it be a vertical translation of 3 units up?

Answer 8

unless I'm reading "parent function" wrong, I think that's all they're doing here... it's a question like your last one that shows you the impact of changing a function somehow, in this case, by adding 3

Answer 9

Yes, nice!
