Answer:
The Domain is where the line on your graph crosses the X axis.
The Range us where the line on your graph crosses the Y axis
And a arrow means it goes Into infinity
Step-by-step explanation:
Say you Have a line, it crosses the X axis at -3, your Domain would be -3!
Now say this line crosses the Y axis at -6, Your Range would be -6!
And now say if instead of the line ending at a dot after crossing -6 It has a arrow, that means you have infinity, Making your range instead of -6 it's be infinity! (If the arrow points up it's positive infinity, If the arrow points down it's negative infinity)
So for the first 2 numbers your answer would be [-3,-6] and in you have infinity itd be [-3, infinity) parenthesis isn't a error btw if you still don't get it I can just reply with a sheet I have on it
Volume of a prism is V=Bh
Answer:
can't see proprly
Step-by-step explanation:
set x=0 to get insights.
at x=0 to the functions are
-2(0-2)²+3 = -5
-2(0+2)²-3 = -11
-2(0-2)²+3 = -5
-2(0-2)²-3 = -11
weird, for some reason option 1 and 3 seem to be the same, maybe that's an accident by the author.
maybe a + was intended inside the parentheses, dunno.
option 1 and 3 seem fine, although I think there is an error in the options. they shouldn't be exactly the same
