We have the expressions:
Now, with this we operate as follows:
a)
Then, the axis is x = -3 and the vertex (-3, 6)
b)
Then, the vertex is (2, 5) and the axis is x = 2.
c)
Then, the vertex is (2, -4) andd the axis is x = 2.
d)
Then, the vertex is (-7/2, -57/4) and the axis is -7/2.
Answer:
= 2n - 3
Step-by-step explanation:
Note the difference in consecutive terms is constant, that is
1 - (- 1) = 3 - 1 = 5 - 3 = 7 - 5 = 2
This indicates that the terms are an arithmetic sequence with
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 1 and d = 2, thus
= - 1 + 2(n - 1) = - 1 + 2n - 2 = 2n - 3
