- 4. Let f (x) = x³ -x² + 5. a) Find the y-intercept of f. y-intercept: b) Find f' and f", and determine where each are 0 and/or do not exist (DNE). If none, write "none". f' = 0: f' DNE: f" = 0: f" DNE: c) E Do a sign analysis on f' and f". d) Find the intervals on which f is increasing and decreasing. Increasing: Decreasing: e) Find the intervals on which f is concave up and concave down. Concave up: Concave down: f) answers as (x, y) points. Find all local maxima, local minima, and inflection points of f. Be sure to write your Local max: Local min: Inflection point(s): -4 -3 -1 g) Sketch the graph of f.arrow_forwardThe temperature in degrees centigrade (°C) at each point (x, y) on a curve 2.x + y = 3 is given by T(x, y) 2x2 + 2x + 5y. Find the lowest temperature on the curve using: Second Derivative Testarrow_forwardLet f(x)be defined on the closed interval [a, b] such that the point a secant line passes through points (a, f(a)) and (b, f(b)) and the distance between a and b is y, using the definition of the derivative, find the derivative off from the given secant line.arrow_forward
- Consider the function h(x) = 1/5 x^5 − 1/3 x^3 + 2. a) Using derivatives, find the interval(s) where ℎ is increasing and the interval(s) where h is decreasing. b) Using the second derivative test, determine the location of each local maximum or minimum. c) Sketch the graph of y = h(x) using the data you gathered in parts a) and b).arrow_forwardDifferentiate the function: f(x) = x secx Select one: a. f'(x) = 3x2 • secx + x · sec x • tan x f'(x) = 3x² · secx tan x b. с. f'(x) = 3x2 · sec x + x³ · sec² x %3D O d. .3 f'(x) = 3x? • sec x - x° • sec x · tan xarrow_forwardExer. 27-32: (a) Use f' to prove that f has an inverse function. (b) Find the slope of the tangent line at the point P on the graph of f. 27 f(x) = x² + 3x³ + 2x-1; P(5, 1)arrow_forward
