Frankie Burns, a 10-year-old, has a raw, sore throat, fever of 101° F, and just feels awful. Laura is going to collect a throat swab from Frankie for a rapid strep test. What bacteria cause strep throat? What is the scientific name of the bacteria? Which of the two names is the genus, and which of the two names is the species?

no they are not always accurate because they can not give you a specific fortune reading they can not tell you exactly what’s gunna happen

golgi body just took the test on edge

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
