Dental assistant a says a child's first dental visit should be around the age of 4, when children start to brush their own teet. dental assistant b says a child's first visit should be around the age of 2. which assistant is correct?

I would say dental assistant B because, The American Academy of Pediatric Dentistry (AAPD) recommends that a child go to the dentist by age 1 or within six months after the first tooth erupts. Primary teeth typically begin growing in around 6 months of age.

Lot of points 7.34 your welcome

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
