Answer:
x g(x + 2)-1 h(x)
-2 g(-2+2)-1 -1
-1 g(-1+2)-1 0
0 g(0+2)-1 1
1 g(1+2)-1 2
2 g(2+2)-1 3
Part A: 3
Part B: -1
Step-by-step explanation:
When you have questions like these all you have to do is plug in and solve.
For example I will do h(2) & h(-2) for reference.
<em><u>h(2):</u></em>

<em><u>h(-2):</u></em>

Answer:
B. Not enough information.
Step-by-step explanation:
We are given that all three angles of ∆DEF is congruent to all the three corresponding angles of ∆XYZ. However, this is is not enough to prove that they are both congruent to each other. There's no information about any of tge side length.
AAA is not a criterion that proves two triangles are congruent.
Therefore, we will conclude that there is not enough information.

Answer:
2
Step-by-step explanation:
0(162/3125)+1(162/625)+2(216/625)+3(144/625)+4(48/625)+5(32/3125)
= 2
Answer:
b. an = 2 • (-3)^(n - 1)
Step-by-step explanation:
Before we test a solution or two, we can easily discard most of them.
We see the values alternate of signs (-5 for the 2nd term and +162 for the 5th term)... so the progression factor has to be negative (in order to alternate sign). <u>That already excludes answers A and C.</u>
Normally, a geometric progression has the (n-1) exponent, not (n+1), so our chances seem to be better with B.
We can test both D and B with n = 2, to obtain -6
Let's test answer D before:

The result is -54, not -6... so it's not the right result.
Let's test answer B then:

Right! Let's verify with n=5 to get 162:

Confirmed, answer is B. an = 2 • (-3)^(n - 1)
