Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 2x - 1

g(x) = 2x + 1

<em>x</em> = -3

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                                                                                                  f(g(-3))
  2. Substitute in <em>x</em> [Function g(x)]:                                                                         g(-3) = 2(-3) + 1
  3. Multiply:                                                                                                             g(-3) = -6 + 1
  4. Add:                                                                                                                   g(-3) = -5
  5. Rewrite:                                                                                                             f(-5)
  6. Substitute in <em>x</em> [Function f(x)]:                                                                           f(-5) = 2(-5) - 1
  7. Multiply:                                                                                                             f(-5) = -10 - 1
  8. Subtract:                                                                                                            f(-5) = -11

Analyze a graph In Exercise,analyze and sketch the graph of the function.Label any relative extrema, points of inflation,and asy
FinnZ [79.3K]

Answer:

Step-by-step explanation:

Given is a function of x

f(x) = xe^{-x}

When y=0 we get x=0 and infinity

Hence x intercept is 0 and one asymptote is x axis.

When x=0 , y =0

f'(x) = e^{-x}(-x+1)

f''(x) = e^{-x}(x-1-1)

Maxima at x=1, and point of inflection is at x=2

Increasing upto x=1 and then decreases
