Q. Write a quadratic function with zeros 9 and −3.Write your answer using the variable x and in standard form with a leading coefficient of 1.f(x)=______
Identify Zeroes: Zeroes are 9 and −3, so the factors are (x−9) and (x+3)
Write Function:f(x)=(x−9)(x+3)
Expand Expression: Expand: f(x)=x(x+3)−9(x+3)
Simplify Expression:f(x)=x2+3x−9x−27
Final Result: Combine like terms: f(x)=x2−6x−27
