The number of home runs per game in Major League Baseball can be approximated by the function f(x) = 0.017x + 0.61, where x is the number of years after 1977 and corresponds to one year of play.Step 1 of 2: What is the value of f (22) and what does it represent?What does f (22) represent?The average change between 1977 and 1999 for the expected number of home runs per game is f(22).The rate of change in expected home runs per game was f(22) in 1999.The total change between 1977 and 1999 for expected home runs per game is f(22).The expected home runs per game was f(22) in 1999.
