Q2) Consider the following table is used to store contact information: Name Company Address Phone1 Phone2 Phone3 ZipCode Joe ABC Jane XYZ 123 456 5532 2234 3211 12345 3421 14454 Chris PDQ 789 2341 6655 14423 The table is considered as not normalized. Explain why? And what is the INF of the table?

Step 1
e., values that cannot be further divided. In this table, the Phone1, Phone2, and Phone3 columns violate this rule because they contain multiple phone numbers separated by spaces. This makes it difficult to search, sort, and manipulate the data in these Show more…

Use the table below to answer the questions that follow: Explain with limit notation what this table seems to indicate about f(x) about with respect to limits. Evaluate lim x->-1 (x^2 + 3x - 4) / (x^2 - 16) Find lim x->5 sqrt(6x - 4) If lim x->2 f(x) = -3 and lim x->2 g(x) = 7, find lim x->2 (x - g(x)) / f(x). Determine where f(x) = 5x / (x^2 + 16) is continuous. Where is the function f(x) below discontinuous? f(x) = { 4, if x < -3 { x^2 - 5, if -3 <= x <= 1 { x + 3, if x > 1
