Answer:
x=(0.45,-4.45)
Step-by-step explanation:
x²+4x=2
x²+4x+(2)²=2+(2)²
x²+(2)²=2+4
(x+2)²=6
√(x+2)²√6
x+2=√6
x=-2±√6
x=-2±2.45
x=(0.45,-4.45)
Answer:
See below.
Step-by-step explanation:
f(x) = -|x + 9|
compared to
f(x) = |x|
has a graph that opens downward in an upside down V shape.
It has been moved 9 units left compared to the graph of f(x) = |x|.
It reflects over the x-axis.
