Answer:
domain is:(-∞,-3]∪ [3,∞)
Step-by-step explanation:
f(x)=√(x²-9)
f(x)=√(x-3)(x+3)
domain is:(-∞,-3]∪ [3,∞)
Answer:
y = x2 - 4x + 2 ; y=x²-4
Step-by-step explanation:
Axis of symmetry = - b /2a
y=x²-2
a = 1 ; b = - 2
x = - (-2) / 2(1)
x = 2/2 = 1
y = x2 - 4x + 2
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
y = x2 + 4x + 2
a = 1 ; b = 4
x = - 4 / 2(1)
x = - 4/2 = - 2
y=x²-4
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
The answer to this is:
1/14
Answer:
It created a single African nation with many states.
It would be 16 since when you replace the k for the 4 it is 4^2 and 4 multiplied by itself (squared)=16. Hope this helps!
