Which of these is the standard form of the following function? f(x)=7(x-1)^2+3 A. f(x)=7x^2-14x+10 B. f(x)=7x^2-14x-10 C f(x)=-7x^2-14x+10 D f(x)=-7x^2-14x-10 D C B A

To find the standard form of the function , we need to expand the expression inside the parentheses and then distribute the 7.Expanding the expression inside the parentheses: Now, distribute the 7: Finally, add the constant term 3: Therefore, the standard form of the function is .The correct answer is A. .
