PRE CALC: I REALLY REALLY NEED HELP PLEASEI WILL GIVE BRAINLIEST A piecewise function f (x) is defined by f of x is equal to the piecewise function of 3 to the power of the quantity x plus 1 end quantity minus 2 for x is less than or equal to 1 and the quantity negative x squared plus x plus 2 end quantity over the quantity x squared minus 3 times x plus 2 end quantity for x is greater than 1

Part A: Graph the piecewise function f (x) and determine the range. (5 points)

Part B: Determine the asymptotes of f (x). Show all necessary calculations. (5 points)

Part C: Describe the end behavior of f (x). (5 points)

Aresearch study is studying the effects of a new drug for osteoporosis alzheimer's disease (ad) for women above the age of 65 years. a group of individuals with osteoporosis is randomized into two groups. one group is treated conventionally, and the second group is treated with the new medication. assessments are made at 3, 6, 12, 36, and 48 months. the conventionally treated group is assessed for ad using a serum blood test, and the treatment group is assessed for ad using a pet radiotracer that binds to beta-amyloid plaques. in comparing these 2 trial arms, the authors of the study may encounter which type of bias? a. selection bias on the risk of developing b. measurement bias c. confounding bias d. recall bias e. lead-time bias
