Find the solution to each of these recurrence relations with the given initial conditions. Use an iterative approach such as that used in Example 10. a) an = −an−1, a0 = 5 b) an = an−1 + 3, a0 = 1 c) an = an−1 − n, a0 = 4 d) an = 2an−1 − 3, a0 = −1 e) an = (n + 1)an−1, a0 = 2 f ) an = 2nan−1, a0 = 3 g) an = −an−1 + n − 1, a0 = 7

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
