Q. f(x)=x2−6x−7Which of the following is an equivalent form of the function f in which the zeros of f appear as constants or coefficients?Choose 1 answer:(A) f(x)=(x−7)(x+1)(B) f(x)=(x−1)(x+7)(C) f(x)=x(x−6)−7(D) f(x)=(x−6)2−7
Factor the quadratic equation: To find the zeros, we need to factor the quadratic equationf(x)=x2−6x−7.
Identify the two numbers: We look for two numbers that multiply to −7 and add up to −6. These numbers are −7 and 1.
Write the factored form: Now we write the factored form using these numbers: f(x)=(x−7)(x+1).
Check answer choices: We check the answer choices to see which one matches our factored form.
Identify correct answer: The correct answer is (A) f(x)=(x−7)(x+1), which matches our factored form.
