Solve this using the y formula and move the x to the right so solve for x and there can’t be decimal when listing 5 values for x or y.

Solution

The given equation is:

y=x3+2y = \sqrt[3]{x} + 2

To solve for xx, we need to isolate xx on one side of the equation. Here's how to proceed step by step:

  1. Subtract 2 from both sides to move the constant term: y2=x3y - 2 = \sqrt[3]{x}

  2. Cube both sides to eliminate the cube root: (y2)3=x(y - 2)^3 = x

Thus, the equation for xx in terms of yy is:

x=(y2)3x = (y - 2)^3

Now, let's calculate some values of xx for integer values of yy (without decimals):

For y=0,1,2,3,4y = 0, 1, 2, 3, 4:

  • When y=0y = 0:
    x=(02)3=(2)3=8x = (0 - 2)^3 = (-2)^3 = -8
  • When y=1y = 1:
    x=(12)3=(1)3=1x = (1 - 2)^3 = (-1)^3 = -1
  • When y=2y = 2:
    x=(22)3=03=0x = (2 - 2)^3 = 0^3 = 0
  • When y=3y = 3:
    x=(32)3=13=1x = (3 - 2)^3 = 1^3 = 1
  • When y=4y = 4:
    x=(42)3=23=8x = (4 - 2)^3 = 2^3 = 8

Therefore, the pairs of xx and yy values are:

  • y=0x=8y = 0 \Rightarrow x = -8
  • y=1x=1y = 1 \Rightarrow x = -1
  • y=2x=0y = 2 \Rightarrow x = 0
  • y=3x=1y = 3 \Rightarrow x = 1
  • y=4x=8y = 4 \Rightarrow x = 8

Would you like more details or have any other questions?

Relative questions:

  1. What would the solution for xx be if y=1y = -1?
  2. How does the behavior of the equation change for negative values of yy?
  3. Can you explain why cubing eliminates the cube root in this context?
  4. What happens to the value of xx as yy increases significantly, say for y=10y = 10?
  5. How would you solve this equation if there were an additional term in the cube root expression?

Tip:

When solving equations involving roots, always consider inversing the root operation to simplify the equation (e.g., cube both sides for cube roots).
