Math Problem Statement

solve

Complete the table of values for y = x^3 + x - 3 and draw the graph of y = x^3 + x - 3 for values of x from -2 to 2.

Solution

Let's complete the table for y=x3+x3y = x^3 + x - 3 by calculating the values for x=1x = 1 and x=2x = 2.

  1. For x=1x = 1: y=13+13=1+13=1y = 1^3 + 1 - 3 = 1 + 1 - 3 = -1

  2. For x=2x = 2: y=23+23=8+23=7y = 2^3 + 2 - 3 = 8 + 2 - 3 = 7

So, the completed table of values is:

\hline x & -2 & -1 & 0 & 1 & 2 \\ \hline y & -13 & -3 & -3 & -1 & 7 \\ \hline \end{array}$$ Next, you would plot these points $$(-2, -13)$$, $$(-1, -3)$$, $$(0, -3)$$, $$(1, -1)$$, and $$(2, 7)$$ on the graph and draw a smooth curve passing through them to complete the graph of the function $$y = x^3 + x - 3$$. Would you like me to provide more details or help with anything else? Here are five related questions for further practice: 1. What is the value of $$y$$ for $$x = 3$$ in the function $$y = x^3 + x - 3$$? 2. Can you find the x-intercepts (roots) of the equation $$y = x^3 + x - 3$$? 3. What is the derivative of $$y = x^3 + x - 3$$ and what does it represent on the graph? 4. How does the graph of $$y = x^3 + x - 3$$ change if you add 2 to the function, making it $$y = x^3 + x - 1$$? 5. What are the turning points of the graph of $$y = x^3 + x - 3$$? **Tip:** When plotting cubic functions, make sure to check for turning points and inflection points to get the correct shape of the curve.
