Answer:
(-infinity, inifinty)
Step-by-step explanation:
the domain should be all real numbers of this quadratic
275??
16×=4400
16×/16=4400/16
x=275
Let's say you had the number 70.
70

5 2
Answer: 7,5,2 are your prime numbers
Its A!
if you plug 4 and -7, the equation works
<span>plug in x=0 gives 0/0. This is one of the indeterminate forms (some others are ∞/∞ and 0·∞) use L'Hospital's Rule.
Differentiate the top and bottom of the fraction:
lim (cos x) / (x - π/2) => lim (-sin x) / (1 - 0)
Now you can substitute x = π/2 without problem
lim = -1/1= -1</span>
