From the calculations in this problem it can be concluded that if a 4.00-cm tall object is placed 45.7 cm from a concave mirror having a focal length of 15.2 cm, then the image will be inverted, 1.99-cm tall and located 22.8 cm from the mirror. The results of this calculation agree with the principles discussed earlier in this lesson.And the inflection point is where it goes from concave upward to concave downward (or vice versa). Example: y = 5x 3 + 2x 2 − 3x. Let's work out the second derivative: The derivative is y' = 15x2 + 4x − 3. The second derivative is y'' = 30x + 4.
