Finish the steps below to write a quadratic function for the parabola shown. Use the vertex form, f(x) = a(x – h)2 + k, and substitute in the values for h and k.
f(x) = a(x – 5)2 + 3
Use another point and substitute in values for x and f(x). Solve for a.
5 = a(6 – 5)2 + 3
Write the function, using the values for h, k, and a.
The function is f(x) =
(x –(blank))2 +(blank).

Imogene invested $8,000 in a bank account that pays 8 percent simple interest at the end of each year. her friend invested the same amount in stocks where the growth of the investment is represented as 2,000 times the square root of 2 less than the time lapsed in years. if y1 and y2 represent the amount earned in dollars and t is the time lapsed in years, which system of equations correctly represents the situation?
