Question 1

Write the equation of a cubic function that has been shifted right 3 units, vertically stretched by a factor of 2 and shifted up 4 units.

Accepted Answer

$$f\left(x\right)=2\left(x-3\right)^3+4$$

Answer

$$f\left(x\right)=2\sqrt[3]{x-2}+4$$

Answer

$$f\left(x\right)=2\left(x^3-3\right)+4$$

Answer

$$f\left(x\right)=2\left(x+3\right)^3+4$$

Question 6

Which equation below could represent the graph shown?

Accepted Answer

$$f\left(x\right)=\sqrt[]{x+3}$$

Answer

$$f\left(x\right)=\sqrt[]{x}-3$$

Answer
