Chapter 3.1, Problem 10QR

Can you elaborate part a?And I don’t understand why for g we have 4^3 choices

Let X = {-3, 1,4, 5, 11, 18}. Let f : X → Z by f(x) = 7x + 6. The range of the function is (-3,18)

Looking at the graphs of f and g, find all values of x where the sum, f+g, of f and g is continuous, expressing your answer in interval notation: A) (-10,-5) U (-5,10) B) (-10,4) U (4,10) C) (-10,10) D) (-10,-5) U (-5,4) U (4,10) E) (-10,-5] U (4,10)

Determine the interval (s) where the following function is continuous x-7 f(x)= (x-7)x+4)

Explain using theorems 4, 5, 7 and/or 9 from section 2.5, why the function f(x) = sin x + Inx is continuous at every number in its domain. Make sure to state the domain of the function and state the domain of each function you state is continuous.

Let 1 f(æ) = - 5, - 3 < x < 6 2 Determine the domain of f-'. Write your answer using Interval Notation. Round to two decimal places as needed. Domain of f-:

Consider the function f(x)=x/x^2+12x+32. Determine the intervals on which f is increasing and decreasing. Your answer should either be a single interval, such as "(0,1)", a comma separated list of intervals, such as "(-inf, 2), (3,4)" , or the word "none".
