Oliga [24]
Answer: \\ We \: have \: \frac{AM}{AC} = \frac{1}{3} , \frac{AN}{AB} = \frac{1}{3} ,\hat{A} \: is \: a \: shared \: angle \\ \Rightarrow \bigtriangleup AMN \cong \bigtriangleup ACB \\ \Rightarrow MN = \frac{1}{3} BC = \frac{1}{3} \times 15 = 5

What is the domain and range for y=sqrt(x-4)
liberstina [14]
The domain of a function is all of the values of x for which the function is defined. If we substitute 4, the answer is 0. However, when any number smaller than +4 is substituted, the equation becomes:
y = sqrt(negative number) which is undefined. Thus, the domain is
D: x  ≥ 4
The range of the function can be determined by the domain. The lowest number the equation will yield is negative infinity because when we take the square root of a positive number, there is one positive root and one negative root. For example, sprt(4) = +2 and -2
Thus, the range is
R: -∞ < y < ∞
