Is a reciprocal of an improper fraction sometimes, always, or never a proper fraction? Explain.
Genrish500 [490]
It is always because if you have an improper fraction, the larger number is always the numerator. To get a reciprocal, you flip the fraction so that the denominator is the numerator, and vice versa. If the numerator is always bigger, and you make it the denominator, it would be proper.

What is the absolute value transformation of this function?
xxMikexx [17]

Answer:

k(x) = -|x + 2| + 3

Step-by-step explanation:

Parent function of the absolute function given in the graph,

f(x) = |x|

1). Function 'g' is reflected across the x-axis, then the image will be,

  h(x) = -f(x) = -|x|

2). Function 'h' the shifted 2 units left and 3 units upwards, image function will be,

  k(x) = h(x + 2) + 3

  k(x) = -|x + 2| + 3

Therefore, the transformed function is k(x) = -|x + 2| + 3.
