The graph of a quadratic function has x intercepts at -3 and 5/2, and y intercept at 10. give the function.

  f(x) = -4/3x² -2/3x +10

Step-by-step explanation:

The quadratic regression function of a graphing calculator or spreadsheet can determine the equation for you.

___

Or, you can determine it yourself.

The equation can be written in the form ...

   f(x) = a(x +3)(x -5/2) . . . . . . . using the given x-intercepts

for some value of "a"

For x = 0, this must match the y-intercept.

  f(0) = a(0 +3)(0 -5/2) = 10

  -15/2·a = 10

  a = -20/15 = -4/3

So, the function can be written as ...

  f(x) = (-4/3)(x +3)(x -5/2)

or

  f(x) = -4/3x² -2/3x +10
