The value of a particular rookie baseball card was $2.00 when it was first printed. Five years later, when the player was at his peak, the card was valued at $25.00. Ten years after printing, the card was valued at $8.00.

Model the above scenario, showing the value of the card, y, with respect to years since it was printed, x. Write the equation in standard form, y = ax2 + bx + c, where a, b, and c are real numbers rounded to the nearest tenth.

jhonyy9 · Answer

let being x_0 the time when the card was printed so and given that then the prise y was $2
- five years later so x_0 +5  the card was valued at $25

- ten years after printing so x_0 +10 the card was valued at $8 
using these details you need drawing a diagram with coordinates X0Y

hope helped
