Math Problem Statement

Use a calculator to evaluate the function at the indicated values. Round your answers to three decimals. h(x) = eβˆ’3x; h

1 3

, h(1.5), h(βˆ’1), h(βˆ’πœ‹) h

1 3

= Incorrect: Your answer is incorrect. h(1.5)

h(βˆ’1)

h(βˆ’πœ‹)

Solution

import numpy as np

Define the function h(x) = e^(-3x)

def h(x): return np.exp(-3 * x)

Calculate h(x) for the given values

values = { "h(1/3)": h(1/3), "h(1.5)": h(1.5), "h(-1)": h(-1), "h(-Ο€)": h(-np.pi) }

Round the results to three decimal places

rounded_values = {key: round(val, 3) for key, val in values.items()} rounded_values{'h(1/3)': 0.368, 'h(1.5)': 0.011, 'h(-1)': 20.086, 'h(-Ο€)': 12391.648}{'h(1/3)': 0.368, 'h(1.5)': 0.011, 'h(-1)': 20.086, 'h(-Ο€)': 12391.648}successHere are the rounded values for the function h(x)=eβˆ’3xh(x) = e^{-3x}:

  1. h(13)=0.368h\left(\frac{1}{3}\right) = 0.368
  2. h(1.5)=0.011h(1.5) = 0.011
  3. h(βˆ’1)=20.086h(-1) = 20.086
  4. h(βˆ’Ο€)=12391.648h(-\pi) = 12391.648

Do you want further explanation or details on how these values were computed?

Here are 5 related questions to expand your understanding:

  1. How does the value of eβˆ’3xe^{-3x} change as xx becomes more positive or negative?
  2. What is the general effect of a negative exponent on the behavior of exponential functions?
  3. How does the base ee influence the properties of eβˆ’3xe^{-3x} compared to other exponential bases?
  4. How would the graph of h(x)=eβˆ’3xh(x) = e^{-3x} look for x∈[βˆ’Ο€,2]x \in [-\pi, 2]?
  5. Can the function h(x)h(x) ever reach a value of 0? Why or why not?

Tip: When rounding intermediate results for exponential functions, always ensure the precision aligns with the context of the problem!
