Question

I need help guys

2. Generate the first 5 terms of this sequence:

f(1) = 2 and f(2) = 3, f(n) = f(n - 1) + f(n - 2), for n > 2.

3.If g(x) = x2 + 3, find g(4).


4.If g(x) = 2(x - 4), find the value of x if g(x) = 20.

5. For the function f(x) = x + 7, what is the ordered pair for the point on the graph when x = 2b?

Answer 2

The first bit is recursive. the sequence starts off 2,3...
the third number is the sum of the previous 2.

so here, 2,3,(2+3),(2+3+3) etc.
2,3,5,8,13

Answer 3

bibby's got this. Byee

Answer 4

plug in 4 into g(x) and solve\[4^2+3\]
and the other\[ g(20)=2(20-4)\]
I love you fizic

Answer 5

Luh you.

Answer 6

Omg bibs you are a life saver

Answer 7

@nincompoop get on number 5 pls as I do not understand it

Answer 8

unless b = 7 cause of y = mx + b in which case x = 14 and yeah

Answer 9

y = mx + b ?? >.>

Answer 10

yep

Answer 11

Wouldn't 7 be your B in y = mx + b?

Answer 12

it is an equation of a line y = mx+b
so substitute x = 2b = 2(7) = 14

Answer 13

Yea, its 14

Answer 14

These are the choices for 5
(2b, 2b + 7)

(2b, x + 7)

(x, x + 7)

(x, 2b + 7)

Answer 15

b is your y-intercept (0,y)

Answer 16

B ?

Answer 17

woohoo 90% thx guys

Answer 18

:o

Answer 19

what? you didn't even answer number 5 lol

Answer 20
