Option B. 3
This is the procedure:
f(0) = 3
f(n+1) = - f(n) +5
f(1) = - f(0) + 5 = - 3 + 5 = 2
f(2) = - f(1) + 5 = - 2 + 5 = 3.
Answers:
When we evaluate a logarithm, we are finding the exponent, or <u> power </u> x, that the <u> base </u> b, needs to be raised so that it equals the <u> argument </u> m. The power is also known as the exponent.
The value of b must be <u> positive </u> and not equal to <u> 1 </u>
The value of m must be <u> positive </u>
If 0 < m < 1, then x < 0
A <u> logarithmic </u> <u> equation </u> is an equation with a variable that includes one or more logarithms.
===============================================
Explanation:
Logarithms, or log for short, basically undo what exponents do.
When going from to , we have isolated the exponent.
More generally, we have turn into
When using the change of base formula, notice how
If b = 1, then log(b) = log(1) = 0, meaning we have a division by zero error. So this is why
We need b > 0 as well because the domain of y = log(x) is the set of positive real numbers. So this is why m > 0 also.
5 hundreds x 10 = 500 x 10 = 5,000
It had to be 56 it can go aby higher than that
The answer should be 4/3!
