Answer:
A quadratic function whose zeros are 2 and 7 is f(x) = x^2 - 9x + 14
If the zeros of a quadratic function are a and b, the quadratic function will be given as:
f(x) = (x - a)(x - b)
For the function f(x) whose zeros are 2 and 7:
f(x) = (x - 2)(x - 7)
Expand the equation
f(x)= x^2 - 7x - 2x + 14
f(x) = x^2 - 9x + 14
Therefore, a quadratic function whose zeros are 2 and 7 is
f(x) = x^2 - 9x + 14
Easy, so in the ratio 2:3
