Answer:
yes, ±2
Step-by-step explanation:
The x-intercepts are found by setting y=0 and solving for x:
x^2/4 = 1
x^2 = 4
x = ±√4
x = ±2
The x-values of interest are -2 and +2.

Answer:
26,244
Step-by-step explanation:
The sequence is geometric with a common ratio of -3. The general term is ...
an = (a1)r^(n-1)
The first term is 4, so we have ...
an = 4·(-3)^(n-1)
For n=9, we find the 9th term to be ...
a9 = 4·(-3)^(9-1) = 4·3^8
a9 = 26,244

<em>Additional comment</em>
When -3 is raised to an even power, the sign of the product is positive, the same as 3 raised to that power.
Answer:
A cube has 6 equal faces, 8 vertices, and 12 edges.
Step-by-step explanation:
My answer is self-explanatory.
Second option
Also, the reason it can not be the third one is because the circle at -3 is shaded in, meaning x can equal - 3, whereas its not present in this inequality: 5 – x > 8
5 - x = 8
+x
5 = x + 8
-8
-3 = x
(when solving for x, make sure its positive, that's why I started of by adding x on both sides. It makes it easier to figure out the values that works of x. )
Hope this helps!
