01. Functions f and g are defined by
f:
x3x-2, XER,
2x + 3
8:X
XER, x1.
x-1
(1) Obtain expressions for f-'(x) and g-'(x), stating the value of x for which g'(x) is not defined.
[4]
what exactly does "stating the value of x for which g'(x) is not defined" supposed to mean?

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
