2 Kelsey has a list of possible functions. Pick one of the g functions below and then describe to Kelsey the key features of gly, including the end behavior, y-intercept, and
zeros
gby = x3 - x2 - 4x + 4
g) = x3 + 2x2 - 9x - 18
gx) = x3 - 3x2 - 4x + 12
og = x3 + 232-256-50
g/2) = 233 + 14x2 - 2x - 14
( idc what one u pick )

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed
