The blue graph is and the red graph is . Function was stretched vertically and reflected in the -axis to produce . Function is = || , as shown above. Determine (−100) to the nearest whole number.

  g(-100) = -200

Step-by-step explanation:

Stretching f(x) vertically by a factor of k makes it be k·f(x). Reflecting that over the x-axis makes it be ...

  g(x) = -k·f(x)

When the stretch factor is 2, as here, the function becomes ...

  g(x) = -2|x|

For x = -100, the value of the stretched, reflected function is ...

  g(-100) = -2|-100| = -2(100)

  g(-100) = -200
