Factour ouf 3
f(x)=3(x²-9)
recognize diference of 2 perfect squres
a²-b²=(a+b)(a-b)
x²-9=x²-3²=(x+3)(x-3)
so
f(x)=3(x+3)(x-3)
seto to zero to find roots
0=3(x+3)(x-3)
0=x+3
-3=x
0=x-3
3=x
roots at x=-3 and 3
Answer: Choice A) There must be a vertical asymptote at x = c
Explanation:
The first limit
says that as x approaches c from the left side, the f(x) or y values approach negative infinity. So the graph goes down forever as x approaches this c value from the left side.
The limit
means that as x approaches c from the right side, the y values head off to positive infinity.
Either of these facts are enough to conclude that we have a vertical asymptote at x = c. We can think of it like an electric fence in which we can get closer to, but not actually touch it.
Answer:
201.06 square inches.
Step-by-step explanation:
The equation to use to find the Area of a circle is given as
πr²
Where r = radius of the circle
In the question, we are given the radius of the circle = 8 inches
Area of the circle = π × 8²
= 201.06 square inches.
