Answer:
A. (-∞, ∞)
B. (-∞, 0) U (0, ∞)
Step-by-step explanation:
A. Though the attached calculator disagrees, the value of the derivative of f(x) is actually defined at x=0. Its value is 0. There is a discontinuity in the second derivative at x=0, but both the derivative and the function are continuous there.
differentiable on (-∞, ∞)
__
B. The derivative is discontinuous at x=0, so is undefined there. The function is differentiable everywhere else.
differentiable on (-∞, 0) U (0, ∞)
_____
The graphs of f(x) and its derivative are red and dotted orange, respectively.
The graphs of g(x) and its derivative are purple and dotted blue, respectively.
There are overlaps, which is why we chose to make some graphs dotted.

Answer:
New line =3*ZX
Step-by-step explanation:
It is given that the isosceles trapezoid is dilated using a scale factor of 1/3
and a line is drawn through the center of the new dilated figure, so
let us suppose that line is EF which is drawn and it will also pass through
the center in similar way the line ZX passes through so after considering this situation, we can come to this point
so new line will be 3 times longer than ZX.
