You'd find the vertical asymptotes by seeing where the denominator equals zero; you can do so by factoring the denominator.
In this case, you can factor the denominator into (x+3)(x+2), so if you set each of those equal to zero you can find the equations of the vertical asymptotes (x=-3 and x=-2).
Answer:
y = 4x² -19x -5
Step-by-step explanation:
When you graph it (or use an appropriate tool), it can help us to figure out that the equation is:
y = 4x² -19x -5
(Quadratic regression = the process of determining the equation of a parabola that best fits a set of data)

Answer:
Yes, there is sufficient evidence to conclude that performance on the problem solving task is lowered by having onlookers.
Step-by-step explanation:
Null hypothesis: The performance on the problem solving task is lowered by having onlookers.
Alternate hypothesis: The performance on the problem solving task is not lowered by having onlookers.
Test statistic (t) = (sample mean - population mean) ÷ (sample sd/√n)
sample mean = 89.8
population mean = 89.1
sample sd = √sample variance = √84.6 = 9.198
n = 21
Degree of freedom = n-1 = 21-1 = 20
Assuming a 5% significance level
The test is a two-tailed test. Critical values corresponding to 20 degrees of freedom and 5% significance level are -2.086 and 2.086
Test statistic (t) = (89.8 - 89.1) ÷ (9.198/√21) = 0.7 ÷ 2.007 = 0.349
Conclusion:
Fail to reject the null hypothesis because the test statistic 0.349 falls within the region bounded by the critical values.
There is sufficient evidence to conclude that performance on the problem solving task is lowered by having onlookers.
