Answer:
standard form is f(x) = ax^2 + bx + c
sample equation: f(x) = 5x^2 + 10x + 5. a=5, b=10, c=5
Step-by-step explanation:
a, b, and c are real numbers in the standard form equation. if a>0 the parabola opens upwards, if a<0 parabola opens downwards

Given:
The arithmetic sequence is −15, −33, −51, −69.
To find:
The nth term of the arithmetic sequence.
Solution:
We have,
−15, −33, −51, −69
Here,
First term: a = -15
Common difference is



Now, nth term of an arithmetic sequence is

Substitute a=-15 and d=-18.



Therefore, the nth term of the given arithmetic sequence is
.
