Final answer:
The factored form of a quadratic function can be found by factorizing the quadratic expression into two binomial expressions. Among the given options, option c) (x - 4)(x - 2) is in factored form.
Step-by-step explanation:
To convert a quadratic function from standard form to factored form, we need to factorize the quadratic expression. The factored form of a quadratic function is written as a product of two binomial expressions. Using the given options:
- (x - 4)(x + 2)
- (x + 4)(x - 2)
- (x - 4)(x - 2)
- (x + 4)(x + 2)
We can see that option c) (x - 4)(x - 2) is in factored form because it is expressed as a product of two binomial expressions. Therefore, option c) is the correct answer.
