Question

Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts?

Answer 1

first, what is the y-intercept of the given graph f(x)

Answer 2

-1? @jigglypuff314

Answer 3

yes :)
then back tracking the g(x)
what is g(x) when x is 0?

Answer 4

0 ? @jigglypuff314

Answer 5

not quite :)
every time x goes up 2, g(x) goes up 4
so from
x g(x)
4 9
2 5
0 1
so y-intercept of g(x) is 1 right?

Answer 6

yes

Answer 7

i still dont get how to find it when x=2

Answer 8

every time x goes up 2, g(x) goes up 4
so every time x goes down 2, g(x) goes down 4

so from x=4 , g(x) =9
to x=2 , g(x)=9-4=5

Answer 9

wait so its 5 ?

Answer 10

no, y-intercept is when x = 0
so from x=2, g(x)=5
x=0 is g(x)=5-4 = 1

Answer 11

so g(x) has a greater y intercept?

Answer 12

correct :)
