Your f(x)=sqrt[x+8]/(x+4)(x-6) is MUCH clearer, but not 100% clear. I will assume that your denominator here is the product of (x+4) and (x-6):
√x+8)
f(x) = ------------------
(x+4)(x-6)
We cannot divide by zero. Thus, x cannot be -4 and cannot be 6.
Thus, the domain is:
(-infinity, -4) or (-4, 6) or (6, infinity).
Answer:
11.968
Step-by-step explanation:
B. y=2x-5
-4y=8x-20
y=-2x+5
2x-5=-2x+5
x=2.5
2x*2.5-5=0
-2x*2.5+5=0
so (2.5,0)
