ANSWER
all real numbers
EXPLANATION
The given absolute value function is
![f(x) = |x + 2|](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%7Cx%20%2B%202%7C%20)
This function is obtained by shifting the graph of
![y = |x|](https://tex.z-dn.net/?f=y%20%3D%20%20%7Cx%7C%20)
to the left by 2 units.
Since the domain of the parent function is all real numbers, the domain of the transformed function is also all real numbers because the shifting the parent function horizontally or vertically does not affect the domain.
Answer:
AC=9 cm
ABC is not a right angled triangle
Step-by-step explanation:
AB=8cm
BC=5cm
22=AB+BC+AC
AC=22-8-5
AC=9
since AC is the longest,
using Pythagoras theorem
AC^2=BC^2+AB^2
9^2=8^2+5^2
81=64+25
81=89
therefore, it is not a right angled triangle
First move +5 to to the other side.
-7x=-16-5
-7x=-21
Then after this devide both sides by negative seven.
X=3
