Determine if the given function is continuous on the given point and intervals. Зх - 3x – 5, xs-1 xS-1 f(x) = {2x² + 5x, Зх - 2, -1

Give the domain of the following function in interval notation.   t(x) =             1                        64 + x^2

Identify where the function f(x) = x³ – 4x? + 8x + 1 is increasing, decreasing, concave up, and concave down. (Give your answer as an interval in the form (*,*). Use the symbol o for infinity, U for combining intervals, and an appropriate type of parentheses "(",")", "[", or "]" depending on whether the interval is open or closed. Express numbers in exact form. Use symbolic notation and fractions where needed. Enter DNE if no such interval exists.) f is increasing on: f is decreasing on: f is concave up on: f is concave down on: Use the graphing utility to graph f. f(x) = 20 y + 10 -20 -10 10 20 -10 powered by Sousep -20
