Step-by-step explanation:
sqrt(-4) = sqrt(4×-1) = sqrt(4)×sqrt(-1) = 2i
Rate of change = difference in y over difference in x.
Rate of change = (33-20)/(3-1) = 13/2
Rate of change = (48-33) /(5-3) = 15/2
The rates are not the same so it isn’t linear.
The rate of change for x=3 and x = 5 is greater.
Is there not more to this problem? maybe thats the final answers
