Answer:
= 1
Step-by-step explanation:
The n th term of an arithmetic progression is
= a + (n - 1)d
where a is the first term and d the common difference
use the 9 th term and 7 th term to find a and d
= a + 8d =
→ (1)
= a + 6d =
→ (2)
Subtract (2) from (1) term by term
2d =
⇒ d = 
Substitute this value into (2) and solve for a
a +
= 
a =
-
= 
Hence
=
+
= 1
g(x)=-2(x+3)^2
The -2 in front is the vertical stretch.
Also, because it is going 3 units to the left, you have to put the 3 on the inside and because it is left you do the opposite and it is +3.
