Question

use a graph to find the following
f(o)

Answer 1

what's the function?

Answer 2

f(0)=

Answer 3

do you mean f(x) = 0 ??

Answer 4

I guess

Answer 5

oh wait nevermind, you have to use the graph and find the corresponding y-value to x=0

Answer 6

where does the line cross the y-axis ?

Answer 7

yes.. I am not understanding graphing

Answer 8

3

Answer 9

good, this is called the y-intercept because its where it intersects the y-axis
that point is (0,3)
x=0
y=3

Answer 10

the domain is {x/ ? }

Answer 11

for a function, f(x) x is always inside the parenthesis
so f(0) means x=0, go to graph and follow the line until the x value is 0 or in this case its the y-axis

Answer 12

domain is all possible x-values, i cant tell you without the graph
is it a straight line?

Answer 13

/\/\/\/

Answer 14

I was able to answer all the other questions graphing is driving me crazy

Answer 15

a graph is just like a map, the x-values tell you where you are left/right or east/west, y-values tell you where you are up/down or north/south
a line is just a bunch of points grouped together
any way you can describe the function or attach the graph?

Answer 16

it says use a graph. I'm sure that there is a graph that belongs to that function. So technically look at the graph and check which point intersect (0,?) and you got your answer to f(0)=?
