Answer:
Domain (x): (-∞ , -1) ∪ (-1 , 3) ∪ (3 , ∞)
Range (y): (3 , ∞) ∪ (-∞ , ∞) ∪ (-∞ , 3) -> (-∞ , ∞)
Step-by-step explanation:
Domain (x): (-∞ , -1) ∪ (-1 , 3) ∪ (3 , ∞)
Range (y): (3 , ∞) ∪ (-∞ , ∞) ∪ (-∞ , 3) -> (-∞ , ∞)
Answer: 5
Step-by-step explanation:
By the inscribed angle theorem.

Answer:
W=20
A=400
Step-by-step explanation:
90+310 for area
Answer:
c = 140
Step-by-step explanation:
y = -7x + 140
-7 x 0 + 140
0 + 140
c = 140
(x = 0, y = c)
(0,140)
There's a bit of ambiguity in your question...
We know that
, which means
.
I see three possible interpretations:
• If
, then

• If
, then

• If
, then
![f(7)=-15=\sqrt[k]{2+7}\implies-15=9^{1/k}\implies\dfrac1k=\log_9(-15)](https://tex.z-dn.net/?f=f%287%29%3D-15%3D%5Csqrt%5Bk%5D%7B2%2B7%7D%5Cimplies-15%3D9%5E%7B1%2Fk%7D%5Cimplies%5Cdfrac1k%3D%5Clog_9%28-15%29)
which has no real-valued solution.
I suspect the second interpretation is what you meant to write.
