Answer:
Step-by-step explanation:
y=x²-2x-1
and y=-3x+5
x²-2x-1=-3x+5
x²+x-6=0
x²+3x-2x-6=0
x(x+3)-2(x+3)=0
(x+3)(x-2)=0
x=-3,2
when x=-3
y=-3×-3+5=9+5=14
when x=2
y=-3×2+5=-6+5=-1
so solutions are (-3,14) and (2,-1)
X values are increasing by 2
y values are increasing by 4

Answer:
Answers are below
Step-by-step explanation:
x y
0 $25,001.00
1 $25,000.95
2 $25,000.90
3 $25,000.86
I graphed the function on the graph below and found the values of y for each value of x.
*My graph showed that the initial value of the printer was $25,001.00, instead of $25,000.00*
