7. (a) List the condition(s) for a function to f(x) be continuous at the point x = c. (b) For the following function g(x), list all possible values of x where the function might be discontinuous. g(x) = 2x + a + √x +3 x + 2 |x + 4 + b x>-2 x < -2 (c) Find values for a and b so that the function g(x) from part (b) is continuous.

q.2     Either f(x) a graphically defined function.   Choose all points in the domain of f(x) (values of x) where f(x) is not continuous.

Consider the function. f(x) = ¹ + 10 Determine the intervals on which f is increasing, decreasing, concave up, and concave down. (Give your answer as an interval in the form (, ). Use the symbol oo for infinity, U for combining intervals, and an appropriate type of parenthesis "(".")", "[","]" depending whether the interval is open or closed. Enter if the interval is empty. Express numbers in exact form. Use symbolic notation and fractions where needed. Enter DNE if no such intervals exists.) f is increasing on: f is decreasing on: f is concave up on: fis concave down on: Identify the asymptotes of f. (Give your answer as a comma-separated list of equations. Express numbers in exact form. Use symbolic notation and fractions where needed. Let y = f(x) and give any asymptotes in the form of an equation in terms of x and y. Enter DNE if no such asymptote exists.) vertical asymptote(s): horizontal asymptote(s): Use the graphing utility to graph f. f(x) = X desmos

A function and its graph are given. f(x) = + 4x2 - 20x – 20 y 250 200 150 100 50 - 10 -5 5 –50 (a) From the graph, estimate where f"(x) > 0. (Enter your answer using interval notation.) Estimate where f"(x) o. (Enter your answer using interval notation.) Find where f"x) < 0. (Enter your answer using interval notation.) Find where f"(x) = 0. (Enter your answers as a comma-separated list.) Find where r(x) has its relative maxima and relative minima. (Enter your answers as comma-separated lists. If an answer does not exist, enter DNE.) relative maxima relative minima
