The function of f(x) = (x-4)(x-2) What is the range of the function?
2 answers:
Answer:
All real numbers greater than or equal to -1
Step-by-step explanation:
f(x) = (x-4)(x-2) = x²-4x-2x+8
f(x) = x²-6x+8
f(x) = [(x)²-2(x)(3)+3²-3²]+8
f(x) = (x-3)²-9+8
f(x) = (x-3)²-1
The function has a least value of -1.
So, the range is also all real values greater than or equal to -1
