Using the graphing tool, determine the function for the graph that passes through the points (2.1,2.4), (4.3,6.8), and (6.1,1.9). f(x) = x2 + x −

  f(x) = -1.18056x² +9.55556x -12.4604

Step-by-step explanation:

As required by the problem statement, technology was used to find the polynomial function that passes through the given points. The coefficients shown above are rounded to 6 significant figures. The exact coefficients appear to be ...

  f(x) = (-1 13/72)x² +(9 5/9)x -(12 221/480)

all but the second one

step-by-step explanation:

cuz that one goes over 180
