Question

Please help me solve these issue. Thanks!

The graph of a function is given (a) Determine the interval (s) on which the function is increasing. (Enter your answer using interval notation.) (b) Determine the interval(s) on which the function is decreasing. (Enter your answer using interval notation.) The average rate of change of a function f(x)-x2 between x=5 and x=7 is average rate of change The graph of a function is given. Determine the average rate of change of the function between the indicated points on the graph (Assume that the points lie on the grid lines.)

Explanation / Answer

a) interval on which function is increasing is

( 0 , 2 )

b) interval on which function is decraesing is

[ -1 , 0 ) U ( 2 , 4 ]

2) f(x) = x^2

between x = 5 to x = 7

average rate of change is

7^2 - 5^2 / ( 7 - 5 )

= 12
