Which function is a quadratic function? O u(x) =x+ 3x^2-8
O vo)= 2x^2+ 8x^3+ 9x
O y() =+3x^2+3x^5+ 4
O zx) = 7x^2+ 2x-3

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

where is abdul's work? don't see that anywhere posted : /

this needs to be the answer format, or else your answer is incomplete.

if the number of years is x, then the equation is

in __ years
