Question

Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k. Their is no choices it is a fill in the blank.

Answer 1

if k were 0, g(x) = f(x)+0= f(x) meaning f(x) and g(x) would be the same

if k is bigger than 0, g(x) would be above f(x)

Answer 2

k will be how far up f(x) moves to get to f(x)

Answer 3

It says for the fill in the blank:
Numerical Answers Expected!

Answer 4

yes, they want to know what k is.
k will be how far up f(x) moves to get to f(x)

Answer 5

i don't understand did you look at the graph?

Answer 6

do you agree g(x) "looks like" f(x), but is above f(x) ?

Answer 7

yes

Answer 8

in other words, if you moved f(x) up, you could get it to lay directly on top of g(x)

how far up do you have to slide f(x) ?

Answer 9

3 units

Answer 10

that means k=3

because f(x)+3 is f(x) "moved up" by 3

Answer 11

okay thanks can you help with another question?

Answer 12
