Answer:

Step-by-step explanation:

The factor theorem states if (x - h) is a factor of a polynomial p(x) then

p(h) = 0

However, p(h) ≠ 0 then the value obtained is the remainder.

Thus

p(3) = - 2

When p(x) is divided by (x - 3) then the remainder is - 2

Answer:

$\frac{bd}{(a + c)} = \frac{3 \times ( - 4)}{ (- 2) + ( - 12)} = \frac{( - 12)}{( - 14)} = \frac{6}{7} \\$

f(1)=72 f(n)=f(n−1)+9 Find an explicit formula for f(n)

myrzilka [38]

$a_{n}$ = 9n + 63

generate the first few terms using the recursive equation

f(1) = 72

f(2) = 72 + 9 = 81

f(3) = 81 + 9 = 90

f(4) = 90 + 9 = 99

the sequence is 72, 81, 90, 99, .....

This is an arithmetic sequence whose n th term formula is

$a_{n}$ = $a_{1}$ + (n - 1 )d

where $a_{1}$ is the first term and d the common difference

d = 99 - 90 = 90 - 81 = 81 - 72 = 9 and $a_{1}$ = 72

$a_{n}$ = 72 + 9(n - 1) = 72 + 9n - 9 = 9n + 63 ← explicit formula
