5. The graph of F(x), shown below, resembles the graph of (*)- *, but it has been flipped over the x-axis, stretched vertically by a factor of 3, shifted down 4 units,
and left 1 unit.
F(x)
Part 1: Write the equation of F(x)

Part 2: Explain how you arrived at the equation from Part 1

Scores on the cognitive scale of the bayley-scales of infant and toddler development range from 1 to 19, with a standard deviation of 3. calculate the margin of error in estimating the true mean cognitive scale score, with 99% confidence, if there are 12 infants and toddlers in a sample.
