F(x)= x^2 -16x+63 find the x-intercepts of this function

(7, 0) and (9, 0)

Step-by-step explanation:

The x-intercepts refers to the points where the graph of the function crosses the x-axis, or simply the zeroes of the function. In this case, we can determine these points analytically or graphically. We simply graph the function;

y = x^2 -16x +63 then determine where the function crosses the x-axis; see the attachment below;

The x-intercepts of this function are;

(7, 0) and (9, 0)

The diameter is twice the radius

Step-by-step explanation:

The radius is the distance from the center of the circle to the outside of the circle

The diameter is from the outer edge of the circle to the outer edge, passing through the center

d = 2r

The diameter is twice the radius
