the dash curve on the graph shows the initial function y=2^{3}\sqrt{x}. what is the equation of the solid curve

Sagot :

Answer:

[tex]y=2\sqrt[3]{x-0.5}+2[/tex]

Step-by-step explanation:

The translated form of a cube root function is:

[tex]y=a\sqrt[3]{x-h}+k[/tex]

where:

  • a stretches or compresses the graph, and reflects it about the x-axis if a < 0.
  • (h, k) is the point of inflection where the concavity of the function changes.

The parent function y = ∛x has a point of inflection at the origin (0, 0).

  • Horizontal Shift: Shifting x by h moves the inflection point horizontally from (0, 0) to (h, 0).
  • Vertical Shift: Shifting y by k moves the inflection point vertically from (h, 0) to (h, k).

In this case, the point of inflection of the dashed curve y = 2∛x is the origin (0, 0), and the point of inflection of the solid curve is (0.5, 2). Therefore:

  • h = 0.5
  • k = 2

So, the equation of the solid curve is:

[tex]\Large\boxed{\boxed{y=2\sqrt[3]{x-0.5}+2}}[/tex]
