| Question 633336:  for each piecewise function, find the specified function values
 f(x)= 3               for x <= -2
 (1/2)x + 6       for x > -2
 f(-5),f(-2),f(0), f(2)
 <= means less than or equal to. i wasnt sure how to do the sign
 for the second equation i (think) that i make for example -5 for x. not sure on first one
 thanks

You can put this solution on YOUR website! Good job with the definition of the function. The <= , and the (1/2)x make me pretty sure that I understand what you mean. As I understand, the function is defined in pieces:
 
  for  and 
  for  and you need to calculate the value of
  for
  ,  ,  and  . 
 
  , and  are in the first part of the domain, the part where
  . In that part,
  , so 
  and  
 
  , and  are in the other part of the domain, the part where
  . In that part,
  , so we enter the x value into  to calculate the  values: For
  ,  so   For
  ,  so  
 The problem does not ask for a graph, but I like to draw these pictures.
 The graph of that piecewise function looks like this:
 
  I drew the function in blue and put green circles around the 4 points (x,f(x)) that we calculated.
