Question

The graph of a function f(x) is shown below:

graph of line going through ordered pairs -2, -1 and 3, 3. An open circle at -2, -1 and a black dot at 3, 3

What is the domain of f(x)?

-2 < x ≤ 3

-2 ≤ x < 3

-1 < y ≤ 3

-1 ≤ y < 3

Answer 1

@hartnn Could you help?

Answer 2

i cannot open the graph.
and you need help with domain only ?

Answer 3

Yes

Answer 4

"open circle at -2,-1"

open circles means x would NOT be = that value.
x would be very near to value of -1 but not equal.

"black dot at 3,3"
black dot or closed circle means x will be = that value
x will be = 3

Answer 5

and for domain, we only consider 'x' values

Answer 6

so domain will go from -2 to 3

Answer 7

So B?

Answer 8

B is exactly opposite...

what we need is that x NOT = -2, because we have open circle there.

-2 < x <<<<<<means x is greater (and NOT =) to -2

Answer 9

Oh!!! OK A??
