Math Problem Statement

Plot five points, f(x)=^3√x +6

Solution

To plot five points for the function f(x)=x3+6f(x) = \sqrt[3]{x} + 6, we will choose five values of xx and compute the corresponding values of f(x)f(x).

Let's compute for x=8,1,0,1,8x = -8, -1, 0, 1, 8:

  1. When x=8x = -8: f(8)=83+6=2+6=4f(-8) = \sqrt[3]{-8} + 6 = -2 + 6 = 4

  2. When x=1x = -1: f(1)=13+6=1+6=5f(-1) = \sqrt[3]{-1} + 6 = -1 + 6 = 5

  3. When x=0x = 0: f(0)=03+6=0+6=6f(0) = \sqrt[3]{0} + 6 = 0 + 6 = 6

  4. When x=1x = 1: f(1)=13+6=1+6=7f(1) = \sqrt[3]{1} + 6 = 1 + 6 = 7

  5. When x=8x = 8: f(8)=83+6=2+6=8f(8) = \sqrt[3]{8} + 6 = 2 + 6 = 8

Thus, the five points are:
(8,4),(1,5),(0,6),(1,7),(8,8)(-8, 4), (-1, 5), (0, 6), (1, 7), (8, 8)

I'll now plot these points for you.

matplotlib.pyplot as plt import numpy as np

Values of x and corresponding f(x)

x_values = np.array([-8, -1, 0, 1, 8]) y_values = np.cbrt(x_values) + 6

Plotting the points

plt.figure(figsize=(6,6)) plt.plot(x_values, y_values, 'bo', label="Points") plt.plot(x_values, y_values, 'r-', label="Curve f(x) = ^3√x + 6") plt.title("Plot of f(x) = ^3√x + 6") plt.xlabel("x") plt.ylabel("f(x)") plt.axhline(0, color='black',linewidth=0.5) plt.axvline(0, color='black',linewidth=0.5) plt.grid(True) plt.legend() plt.show()Here is the plot for the function f(x)=x3+6f(x) = \sqrt[3]{x} + 6 with the five points:
(8,4),(1,5),(0,6),(1,7),(8,8)(-8, 4), (-1, 5), (0, 6), (1, 7), (8, 8)

Would you like more details on how the graph behaves, or do you have any further questions?

Related Questions:

  1. What happens to f(x)f(x) as xx approaches very large or very small values?
  2. How does the graph of f(x)=x3+6f(x) = \sqrt[3]{x} + 6 compare to the graph of f(x)=x+6f(x) = \sqrt{x} + 6?
  3. Can you calculate the slope of the tangent line at one of the points (e.g., at x=0x = 0)?
  4. How would the graph change if we added a constant to xx (e.g., f(x)=x+23+6f(x) = \sqrt[3]{x + 2} + 6)?
  5. What is the inverse of the function f(x)=x3+6f(x) = \sqrt[3]{x} + 6?

Tip: The cube root function is continuous and smooth across all real numbers, unlike square roots which are restricted to non-negative values of xx.
