<h3>
Answer: b = 4 and c = 7.</h3>
===============================================
Explanation:
Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.
The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.
Plug those three values into the vertex form below
y = a(x-h)^2 + k
y = 1(x-(-2))^2 + 3
y = (x+2)^2 + 3
Then expand everything out and simplify
y = x^2+4x+4 + 3
y = x^2+4x+7
We see that b = 4 and c = 7.
Answer: 29 miles per gallon.
Reasoning: 856 miles/29.4 gallons = 29.1156462585 (rounded to the nearest mile = 29)

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*
