Functions Help ! @campbell_st

Answer 1

you see that all x-coordinates in the chart are all same (this chart is g(x) ).

Does the fact that all x values on the line are same, tell you anything about the line?

Answer 2

erm... its vertical ?

Answer 3

yes

Answer 4

it is a vertical line, and in this case (to be specific) it is x=2.
(saying that no mater what the y is, x is 2)

will a vertical line have a y-intercept?
or to be precise -- will the line x=2 ever hit the y-axis?

Answer 5

nope

Answer 6

yes, exactly. the graph of (the line) x=2 will never hit the y-axis.
That means that it (just like any other vertical line, besides y=0) will NOT have any
y-intercept.

Answer 7

So, have you had a y-intercept for g(x), you would be able to say something about the relation of the y-intercepts of the function (right ?)

But if a y-intercept for g(x) does not even exist, then what is your answer ?

Answer 8

im confused

Answer 9

if g(x) has no y-intercept, and f(x) does have one, can you determine the relationship between the y intercepts ?

Answer 10

they r not the same ?

Answer 11

If I say what color is something that is not there, you won't be able to tell me the color (even if you normally have the best eye sight).

Answer 12

Now, you can you determine the relationship between a y-intercept of f(x)
(i.e the point (2,0) ) AND the y-intercept of g(x) that doesn't exist ?

Answer 13

you can't determine the relation between a person that exists and the person that does not exist.

Answer 14

now, think of this same statement, but instead of persons use y-intercepts

Answer 15

So its D ?

Answer 16

Yes

Answer 17

thank you
