Vertical asymptotes occur when the denominator = 0.
f(x) = 4x + 8 / (x + 4)(x - 1)
when x = -4 and x = 1 the denominator = 0
so the required asymptotes are x = -4 and x = 1
Using proportions, it is found that Mason ran 620 meters.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Considering the ratio, the <em>rule of three</em> is given as follows:
2 laps for Mason - 3 laps for Laney.
n meters for Mason - 930 meters for Mason.
Applying cross multiplication:
3n = 930 x 2
n = 930 x 2/3
n = 620
Mason ran 620 meters.

4(4) -4 = 16-4 = 12
She was wrong because she thought that x= 6
