The functions f(x) and g(x) are differentiable. The function h(x) is defined as: h(x)=f(x)+g(x)
If f(6)=
–4, f′(6)=
–3, g(6)=
–6, and g′(6)=6, what is h′(6)?
Simplify any fractions.
h′(6)=

Two groups of students were asked how many hours they spent reading each day. the table below shows the numbers for each group: group a 1 2 1 1 3 3 2 2 3 group b 3 2 3 2 2 2 1 1 2 based on the table, which of the following is true? the interquartile range for group a students is 0.5 less than the interquartile range for group b students. the interquartile range for group a students is equal to the interquartile range for group b students. the interquartile range for group a employees is 0.5 more than to the interquartile range for group b students. the interquartile range for group a employees is 1 more than the interquartile range for group b students.
