Question

Explain what each of the following mathematical statement mean in regard to the graph of f(x).
(1)f(2)=0
(2)lim x->0 f(x)=-infinity
(3) lim x->3+ f(x) = - infinity
(4)lim x->3- f(x)=infinity
(5) lim x->+/- infinity f(x)=0

Answer 1

1.x-2 is a factor of f(x)

2.the valueof f(x) is very very large as the value of x approaches zero

3.as the value of x approaches3 from the right f(x)is very very large

4.as the value of x approaches 3 from the left f(x) is very very large

5.the limit of f(x) as x approaches +/- infinity is zero

Answer 2

1) this says that when you replace the x with the number 2 in f you will get 0
thus intersects the x-axis
2) y ... i dont lime these questions.....
