Q. Write a quadratic function with zeros 0 and 9.Write your answer using the variable x and in standard form with a leading coefficient of 1.f(x)=______
Zeroes of the function: Zeroes of the function: 0 and 9. To find the factors, we use the fact that if 0 is a zero, then x is a factor, and if 9 is a zero, then (x−9) is a factor.
Factored form: The quadratic function in factored form is f(x)=x(x−9).
Expand factors: Now we'll expand the factors to get the standard form: f(x)=x×x−x×9.
Multiplying to get standard form: After multiplying, we get f(x)=x2−9x.
