Answer:

f(n) = -11 + 22(n - 1)

<em>f(1) is your initial value.</em>

f(1) = -11 + 22(1 - 1)

f(1) = -11

------------------------------------------------------------

f(2) = -11 + 22(2 - 1) = 11

f(3) = -11 + 22(3 - 1) = 33

f(4) = -11 + 22(4 - 1) = 55

<em>f(n - 1) is just a notation for the previous term</em>

<em>Using the equation f(n) = f(n - 1) + _______ :</em>

f(2) = f(1) + ??? = 11

f(3) = f(2) + ???  = 33

f(4) = f(3) + ???  = 55

f(2) = -11 + ??? = 11

f(3) = 11 + ???  = 33

f(4) = 33 + ???  = 55

f(2) = -11 + 22 = 11

f(3) = 11 + 22  = 33

f(4) = 33 + 22  = 55

∴ f(n) = f(n - 1) + 22

Graph both functions to find the solution(s) to the system.
Sliva [168]
F(x) = -2x +1 ( slope = -2 y intecept is 1)

replace x with 0 and solve for y  =-2(0)+1 = 1 ( 0,1)
 replace x with 2 and solve for y: -2(2) +1 = -4+1 = -3   (2,-3)

plot those 2 coordinates and draw a line

this is the red line on the attached graph

do the same for the g(x) formula
