Question

Write a quadratic function x-formula"> whose only zero is 12.

Answer 1

Answer:

• f(x) = (x - 12)²

Step-by-step explanation:

If a quadratic function has only one zero, then it has multiplicity of two as it is a second degree polynomial and should have two roots. Since one root is a real number, the second root is also a real number being same as the first number.

The function could be:

• f(x) = (x - 12)²

Answer 2

We know the rule for single zero of quadratic equations

$\\ \sf\longmapsto g(x)=(x-n)^2$

$\\ \sf\longmapsto g(x)=(x-12)^2$
