By the Intersecting Secants Theorem we have
2x(2x+7)=x(x+23)
4x^2+14x=x^2+23x
3x^2=9x
3x=9
x=3
Since DY is length 2x,
the length of DY is 6.

Answer:
Domain: (-∞,∞)
Range: {3}
Step-by-step explanation:
The domain is the x-values of the function, and the range is the y value of the function.
F(x)=3 is really just a fancy way of saying y=3. The range is 3.
Since the function makes a horizontal line, the domain is ∞.
