Suppose that the functions at and w are defined as follows. u(x)=x+2 w (x): 2x2+1 Find the following. Suppose that the function g is defined, for all real numbers, as follows. 1 ExZ x2 g(x)= 2 x=2 Find g(4), g(2), and g(2). O The function g is defined as g (x)= -5x + 3x Find g (x + 1). Write your answer without parentheses, and simplify it as much as possible. g (x + 1) = [ X 5The entire graph of the function g is shown in the figure below. Write the domain and range of g as intervals or unions of intervals. 5 - 4- 3- domain = (0,0) [0,0] (0,0] 2- range = [0,0) O OVO 2 2 3 - OO -2- -3 X 5 -5 -v Determine the interval()_ on which the function is (strictly) decreasing. Write your answer as an interval or list of intervals. When writing a list of intervals, make sure to separate each interval with a comma and to use as few intervals as possible.
