Answer:
f ( x ) = x² - 1
Step-by-step explanation:
hope this will help
I suppose that would just be when the numerator of the rational expression equals zero. Nothing special goes on with the graph in that case; there are simply x-intercepts at those values of x.
<span>Discontinuities are created when the denominator of the rational expression equals zero (because division by zero is undefined). Graphically, this is usually represented by a dashed vertical line indicating a vertical asymptote. </span>

Answer:
B. x = 5/2
Step-by-step explanation:
quadratic formula is:
(
±
)/2a
when
+ bx + c = 0
in this equation, a = 1, b = -5, c = 25/4
plug those into the equation and simplify to get x=5/2
(because b^2-4ac in this case is equal to 0, there is only one answer)
Answer:
169π or 530.93
Step-by-step explanation:
The formula for the area of a circle is πr²
Here, the radius is given to be 13.
So, let's just plug it into the formula as r
π x 13²
π x 169
169π
The radius is 169π. If you want to multiply out the π you would get 530.93, which is equivalent of course.
