Q. Consider the function f(x)=−31(x−2)2+1. Algebraically determine which of the following are the zeros for f(x). Select all correct answers below.(A) 0(B) 3+2(C) 4(D) 2+3(E) 3−2(F) 2−3
Define Zero of Function: Understand what a zero of a function is.A zero of a function is a value of x for which the function equals zero. To find the zeros of f(x), we need to solve the equation f(x)=0.
Set Function Equal: Set the function equal to 0 and solve for x. We have f(x)=−(31)(x−2)2+1. To find the zeros, we set f(x) to 0: 0=−(31)(x−2)2+1
Isolate Squared Term: Isolate the squared term.Add (31)(x−2)2 to both sides to isolate the squared term:(31)(x−2)2=1
Eliminate Fraction: Multiply both sides by 3 to eliminate the fraction.3×(31)(x−2)2=3×1(x−2)2=3
Take Square Root: Take the square root of both sides.(x−2)2=±3x−2=±3
Solve for x: Solve for x by adding 2 to both sides.x=2±3
Identify Solutions: Identify the two solutions.The two solutions are:x=2+3x=2−3
Check Answer Choices: Check the answer choices against the solutions.The correct answer choices that match our solutions are:D) 2+3F) 2−3
