# Math Help - max, min and average to resultant function

1. ## max, min and average to resultant function

hi, i have these 3 functions

i must calculate the resultant function, and to find the max, min and the average.. i have tried to calculate it, i have found these values (max=53; min=38; average=43) but the solution in my book are different (max=54; min=19; average=34).. can you help me?? thank you!!

2. ## Re: max, min and average to resultant function

What do you mean by "resultant function"? I know what the "resultant" of vectors is (the sum of the vectors) but I don't know what is meant by "resultant function".

3. ## Re: max, min and average to resultant function

sum of the three functions

$f_1(t)$ max value is 35, min is 15

$f_2(t)$ ... these are just intervals (I think) what does "19per10" mean???

you have some clarification to do if you want some help with this.
