Answer:
B. negative infinity < x < positive infinity
Step-by-step explanation:
When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for <u>all</u> exponential functions, including this one.
lmk if im incorrect about anything, hope this helps :)
Answer:
x > -5
Step-by-step explanation:
-3x > 15
divide by -3
x > -5
Answer:
The options are not clearly written but, the volume of square based pyramid is 1/6 the volume of a cube because each of the six faces of the cube will contain one square based pyramid.
Step-by-step explanation:
Let the length of each side of your cube be x
the height of each of the six enclosed pyramids would be x/2. So the volume of each pyramid would be given by:
V = (1/3) × base area × height
V = (1/3) × x^2 × (x/2) = (x^3)/6
4: No (2 x 4=8+7=16)
5: Yes (-6 x 5= -30 +10=-20)
6: Yes (27 / 3=9 - 7=2)
7: Yes (5 x 4=20 + -8=12)
8: No ( -16/-4= -4 + 3=-1)
9: Yes (3/4 x 20/1=60/4=15)
It is 0.4. 14/10 is 1.4 then -1 = 0.4
