What is the range of possible sizes for side x?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
