Question
I keep getting this wrong. I’m not used to fractions or Decimals with piece wise functions.. here is my work. I used the rate of change formula (change y / change x = slope) and got a fraction 2.5/3 but I turned it to a decimal - 0.83(repeating). Pls let me know what I should do to get the correct answer. I don’t think I am calculating right.
