2. Evaluate f(x) = 3x+5/x-1 at x = 3

Mathematics
1 answer:
pashok25 [27]3 years ago
6 0

Answer

Let f(x) = ax + b

Then

f(x + 1) = a(x + 1) + b

= ax + a + b

Hence, a = 3, and a + b = 5, b = 2

f(-2) = 3(-2) + 2

= -6 + 2

= - 4

f(2x) = 3(2x ) + 2

= 6x + 2

Archy [21]
Factorize

(3n + 8) (3n - 8) = 0
3n + 8 = 0 and 3n - 8 = 0

Solve both for n

3n + 8 = 0
3n = -8
n = -8/3


3n - 8 = 0
3n = 8
n = 8/3

Therefore n = -8/3 and n = 8/3
