Which function in vertex form is equivalent to f(x)=4+x^2-2x

a) f(x)=(x-1)^2+3
b) f(x)=(x-1)^2+5
c) f(x)=(x+1)^2+3
d) f(x)=(x+1^2+5

so what is the question

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
