( - ∞, 3) ∪ (3, ∞ )
The domain is the set of values of x which make f(x) defined
The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be.
solve x - 3 = 0 ⇒ x = 3
domain : (- ∞, 3) ∪ (3, ∞ )
Answer:
-63 is the answer.
There is a discontinuity at x=1
Step-by-step explanation:
5 hours
75 + 55x = 350
75 - 75 + 55x = 350 - 75
55x = 275
x = 5
all of them
