I could be wrong here, but I think n is 4? I plugged it in, but I was a bit unsure of what you were asking. Wish you the best!
Answer:
No
Step-by-step explanation:
To determine if the 3 sides form a right triangle.
Use the converse theorem of Pythagoras.
If the square of the longest side is equal to the sum of the squares of the other two sides then the triangle is right,
longest side = 14 and 14 ² = 196
9² + 12² = 81 + 144 = 225
Since 196 ≠ 225 the triangle is not right
Step-by-step explanation:
option B is correct answer ( Acute angle triangle)

Answer:
The domain is
and its range is 
The y-intercept is (0,3).
Step-by-step explanation:
Consider the parent function
Its domain is
and its range is 
The graph of the function
is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the domain and will change the range of the function, thus the domain is
and its range is 
To find th y-intercept you have to find y at x=0:

Hence, the y-intercept is (0,3).
