You can use a graph to evaluate functions. identify theof a point on the graph the input is the coordinate and the output is the coordinate.

You can use a graph to evaluate functions.identify the location of a point on the graph the input is the X- coordinate and the output is the y- coordinate.

* But (location) I'm not sure about it

I hope I helped you^_^

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

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.
