if we do a <u>vertical line test</u> on that graph, we'll find that a vertical line will pass by and hit the line only once on its way down, only once meaning the graph is the graph of a function.
<h2>Range</h2>
well, is really how high and low it goes or namely over the y-axis.
well, it goes up up up to 3 then U-turns and back down it goes, now the graph has arrowheads, meaning the graph keeps on going towards infinity, vertically as well as horizontally since it's a parabola, so the range will be
<h2>[3 , +∞)</h2>
<h2>Domain</h2>
well, is simply how left and right it goes or namely over the x-axis.
judging from the arrowheads it moves from infinity to infinity, so
<h2>(-∞ , +∞).</h2>
Answer:
C
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5 → C
Answer: just divide 44.88 by 12 so you will get 3.74
Step-by-step explanation:
Answer: y = 90 x = 29
Step-by-step explanation:
X + y > = 15.....this is saying that small rugs (x) + medium rugs (y) when made, are greater then or equal to 15...because they have to make at least 15
and since small rugs take 2 hrs......2x....and medium rugs take 3 hrs....3y...and they have to be made in less then 60 hrs...
2x + 3y < 60 <=== ur answer
