What is the best method for determining an improvement curve slope

You calculate the derivative of a given function f(x), f'(x), and see when it is positive:

f'(x) > 0

It will give you an interval of values where the slope is positive.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

they charge the same amount at 20 minutes.
