If f(x)=x²−4x+4 and g(x)=x−2, what is the value of (fg)(x) at x=2?

Answer and explanation

Correct answer: 0

The product function is defined by (fg)(x)=f(x)g(x). At x=2, f(2)=2²−4(2)+4=4−8+4=0, while g(2)=2−2=0. Therefore (fg)(2)=0×0=0, so option A is correct. This also follows from the zero-product property: if at least one factor is zero, their product is zero. Option B and option D confuse the product with a value from one factor or involve an arithmetic sign error. Option C may result from evaluating only 2² and ignoring the remaining terms. Both functions are defined at x=2 because they are polynomials, so no domain restriction changes the calculation.
