Question:
Approximate log base b of x, log_b(x).
Of course x can't be negative, and b > 1.
Answer:
f(x) = (-1/x + 1) / (-1/b + 1)
Step-by-step explanation:
log(1) is zero for any base.
log is strictly increasing.
log_b(b) = 1
As x descends to zero, log(x) diverges to -infinity
Graph of f(x) = (-1/x + 1)/a is reminiscent of log(x), with f(1) = 0.
Find a such that f(b) = 1
1 = f(b) = (-1/b + 1)/a
a = (-1/b + 1)
Substitute for a:
f(x) = (-1/x + 1) / (-1/b + 1)
f(1) = 0
f(b) = (-1/b + 1) / (-1/b + 1) = 1
Answer:
N= -4
Step-by-step explanation:
<em>If he draws at random there is a </em><u><em>3/7 percent chance that he will pull an odd number </em></u><em> Here's why :</em>
<em />
- There are seven numbers making the denominating factor 7 and out of those 7 factors only 3 of them are odd numbers
- Making the nominating factor 3 so it should look like this
- 3/7 because three off the seven numbers are odd
- so therefore there is a 3/7 percent chance at pulling an odd number.
