The domain is the whole set of x values, so the domain would go from -infinity to positive infinity. The vertex would be (-5,0) because that is the lowest point on the graph. The Range would include -5 and go up to infinity.
Answer:
A line with a slope of – that passes through the point (–14, 4)
Step-by-step explanation:
The equation of a line is typically written as y= mx+b where m is the slope and b is the y- intercept.

Answer:
the probability is 9/71 ( 12.67%)
Step-by-step explanation:
defining the event Te= the test indicates tuberculosis , then the probability is:
P(Te)= probability of choosing a subject that has tuberculosis * probability that the test indicates tuberculosis given that a subject with tuberculosis was chosen + probability of choosing a subject that has not tuberculosis * probability that the test indicates tuberculosis given that a subject that has not tuberculosis was chosen = 8/1000 * 90/100 + 992/1000 * 5/100 = 0.0568
After this, we can use the theorem of Bayes for conditional probability. Then defining the event Tu= choosing a subject that has tuberculosis, we have
P(Tu/Te)= P(Tu∩Te)/P(Te) = 8/1000 * 90/100 / 0.0568 = 9/71 ( 12.67%)
where
P(Tu∩Te) = probability that a subject with tuberculosis is chosen and the test indicates tuberculosis
P(Tu/Te)= probability that a subject with tuberculosis was chosen given that the test indicates tuberculosis
