5. Consider the function f(x)=
x-1+2 over the interval -7 <x<9.
(a) Graph f(x) over this domain interval only.
(b) State the range of the function over this interval.
f(b)-f(a)
(c) Recall that the average rate of change over the interval a sxsb is calculated by -
1 . Find
b-a
the average rate of change of f(x) over the intervals below:
(i) 25x39
(ii) OSXS1
(iii) -75x59
Do we do these problems??
