Math Problem Statement

Complete the following table for y = x^2 + 3x - 2.

Solution

To complete this table for the function y=x2+3x2y = x^2 + 3x - 2, let's calculate each row step-by-step for the given values of xx:

  1. Calculate x2x^2 for each value of xx:

    • x=1x = -1: x2=(1)2=1x^2 = (-1)^2 = 1
    • x=0x = 0: x2=02=0x^2 = 0^2 = 0
    • x=1x = 1: x2=12=1x^2 = 1^2 = 1 (already provided)
    • x=2x = 2: x2=22=4x^2 = 2^2 = 4
    • x=3x = 3: x2=32=9x^2 = 3^2 = 9
  2. Calculate 3x3x for each value of xx:

    • x=1x = -1: 3x=3(1)=33x = 3(-1) = -3
    • x=0x = 0: 3x=3(0)=03x = 3(0) = 0
    • x=1x = 1: 3x=3(1)=33x = 3(1) = 3 (already provided)
    • x=2x = 2: 3x=3(2)=63x = 3(2) = 6
    • x=3x = 3: 3x=3(3)=93x = 3(3) = 9
  3. Calculate y=x2+3x2y = x^2 + 3x - 2 for each value of xx:

    • x=1x = -1: y=132=4y = 1 - 3 - 2 = -4
    • x=0x = 0: y=0+02=2y = 0 + 0 - 2 = -2
    • x=1x = 1: y=1+32=2y = 1 + 3 - 2 = 2 (already provided)
    • x=2x = 2: y=4+62=8y = 4 + 6 - 2 = 8
    • x=3x = 3: y=9+92=16y = 9 + 9 - 2 = 16

Now, I'll place these values into the table:

\hline x & -1 & 0 & 1 & 2 & 3 \\ \hline x^2 & 1 & 0 & 1 & 4 & 9 \\ \hline 3x & -3 & 0 & 3 & 6 & 9 \\ \hline -2 & -2 & -2 & -2 & -2 & -2 \\ \hline y & -4 & -2 & 2 & 8 & 16 \\ \hline \end{array}$$ Would you like more details or have any questions? Here are some related questions to explore further: 1. How would the table change if the equation were $$y = x^2 - 3x + 2$$? 2. Can we determine the vertex of the parabola represented by $$y = x^2 + 3x - 2$$? 3. What would the values be if we extended the table to include $$x = 4$$? 4. How does changing the coefficient of $$x^2$$ affect the shape of the parabola? 5. Could you plot the points from this table to visualize the graph of the function? **Tip:** Completing tables like this is useful for understanding how each term in a polynomial affects the output.
