4. The cube root parent function is vertically stretched by a factor of 3, reflected in the x-axis,
Mademuasel [1]

Using translation concepts, it is found that the equation that represents the new function is:

  • y = -3\sqrt[3]{x} - 8

The cube root parent function is given by:

y = \sqrt[3]{x}

<h3>Translation:</h3>

The function goes through these following translations:

  • Vertically stretched by a factor of 3, that is, it is multiplied by 3, hence y = 3\sqrt[3]{x}.
  • Reflected over the x-axis, that is, it is multiplied by -1, hence y = -3\sqrt[3]{x}.
  • Translated 8 units down, that is, 8 is subtracted from the function, hence y = -3\sqrt[3]{x} - 8.

Then, the equation is:

  • y = -3\sqrt[3]{x} - 8

Answer:

<u>2,365,200,000 times</u>

Step-by-step explanation:

<u>Given</u> :

  • Average heartbeat rate = 60 times/minute
  • Avg. human lifespan = 75 years

<u>To Find</u> :

  • Number of heartbeats in lifetime of 75 years

<u>Solving</u> :

  • Let the number we require be n
  • n = average heartbeat rate x 60 x 24 x 365 x 75
  • n = 60 x 60 x 24 x 365 x 75
  • n = 3600 x 24 x 365 x 75
  • n = 86400 x 365 x 75
  • n = 31536000 x 75
  • n = <u>2,365,200,000 times</u>
