Step-by-step explanation:
f(-3)= -(-3)2 + 6(-3)
= -(-6) -18

I’m not 100 percent sure someone can comment on this and confirm but when it’s written like a fraction it means division.

Answer:
Step-by-step explanation:
The sequence above is a geometric sequence.
The common ratio (r) =
The common ratio < 1, therefore, the formula for the sum of nth terms of the sequence would be:
a1 = 3
r = -2
n = 6
Plug in the values into the formula
1x78=78
2x39=78
6x13=78
Hope that helped:)
