Answer: The vertex of the given function is (-4,0).
Step-by-step explanation:
Since, the standard form of an absolute function is,
y = a|x-h| + k
Where (h,k) is the vertex of the function,
Here, the given function is,
y = -|x+4|
⇒ y = (-1)|x-(-4)| + k
By comparing,
We get, a = -1, h = -4 and k= 0
Hence, the vertex of the given function is (-4,0).
Hello Nancy
9x>117
Divide both sides by 9
9x/9>117/9
x>13
