r-s At each of the points (8, 8, ). (..), (-3, 3,), evaluate the function w(r, s, t) = sin() or indicate that the function is undefined there. (Use symbolic notation and fractions where needed. If the function is undefined at the given point, type UNDEFINED.) w (8,8, ) = UNDEFINED Incorrect w ( ½, ½, π) = W UNDEFINED (-3,3,4)= -12

Find the transition points. y = 10x³ + 240x² (Use symbolic notation and fractions where needed. Give your answer in the form of a comma separated list) X = -16,0 Incorrect Find the interval(s) of increase. (Use symbolic notation and fractions where needed. Give your answer as interval(s) in the form (*, *). Use the symbol o for infinity, U for combining intervals, and an appropriate type of parenthesis "(", ")", "[", "]" depending on whether the interval is open or closed. If the interval does not exist, enter Ø). x E (-∞,–16),(0,0) Incorrect

At each of the points (20, 2), (3, −6), (½, ½), evaluate the function h(x, y) = undefined there. h(20, 2) = (Use symbolic notation and fractions where needed. If the function is undefined at the given point, type UNDEFINED.) h(3,-6)= √x-y x-y h ( ²⁄², ½ ) = or indicate that the function is Question Source: Rogawski 4e Calculus Early Transcendentals
