Joanna ran a mile in physical education class. after resting for one hour, her heart rate was 60 beats per minute. if her heart rate decreased by 2/5 what was her heart rate immediataly after ahe ran the mile?

Let

x------> Joanna's heart rate immediately after ran the mile

we know that

therefore

the answer is

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.
