The domain of the function is the value of the independent variable, or simply the x-values. The range is the value of the dependent variable, or the y-values. You can determine its domain and range if the curve of the function passes through their coordinates. Hence,
A. True. If you extend the curve downwards, its opening widens and would then encompass all x-values
B. True.
C. False. This is contradictory to A.
D. True. This is same with B.
E. False. This is contradictory to B.
F. False, the origin is at (0,2). It does not extend upward.
The answers are A, B and D.
Answer:
105°
Step-by-step explanation:
This is most likely the answer if the lines are perpendicular... But if It doesn't give you an image of the 2 angles, then the answer is 105°
Answer:
x ≈ 37.13°
Step-by-step explanation:
using the sine ratio in the right triangle
sin x = 
= 
, then
x = 
( ) ≈ 37.13° ( to the nearest hundredth )
If (x+2) is a factor of 3x^2+14x+k, the equation must equal zero when x=-2 so:
3(-2)^2+14(-2)+k=0
12-28+k=0
-16+k=0
k=16
Answer:
0
