***The answer is NOT (5√2, 10)
Identify the open intervals on which the function is decreasing. (Enter your answers using interval notation.)
y=x*√ (100-x^2)
interval: (?, ?)
***The answer is NOT (5√2, 10)
Determine the horizontal asymptote of each function. If none exists, state that fact. answer 45,47,55
Find the interval in which the function f(x) = (x +9)4 + 6 is increasing.
(Use symbolic notation and fractions where needed. Give your answers as intervals in the form (*, *). Use the symbol ∞ for
infinity, U for combining intervals, and the appropriate type of parenthesis "(", ")", "[" or "]" depending on whether the interval
is open or closed.)
