Question

I do not understand this..
Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k.

k = ______

Answer 1

OK! So, the main idea of this is that f(x) is the NORMAL function. g(x) is what happens when you take f(x) and add some number to it

Answer 2

if g(x) was f(x) + 2, for instance, g(x) would be 2 UNITS ABOVE f(x)
So, how many units is g(x) above f(x) in the picture?

Answer 3

is it three?

Answer 4

yes!
So that means that g(x) = f(x) + 3, so k = 3. Good job!

Answer 5

Thank you for helpingg :D

Answer 6

no problem! :)
