From -4 to +4   what is the lowest (relative minimum) point?   And where....    at   -3   and + 3   it  is  -36

Where is it highest (relative maximum) over the interval from  -4  to 4 ?    At 0 it is 64

Nickolas......we are not here to do all of your homework....this is VERY similar to MANY of your other postings....try to find ananswer yourself and then ask a question if you have one.....

No.....sorry..... I meant what do YOU think the answers are?

4 x 3^4 = 324

What are YOUR answers, Nickolas?    Why?

The car travels a total of  120 + 120 = 240 miles

rate x time = distance

time = distance/rate

time = 240mi / 45 mi/hr = 240/45 = 5.3333333333333333 hr

120 mi / 60 mi/hr = 2 hours for first leg of the trip

Return trip takes   5.33333 - 2 hours = 3.33333 hrs

rate times time = distance

rate = distance/time    

rate = 120 / 3.3333 = 36  mi /hr                

Yes........

Just put in the functions you are given...where they intersect is the solution(s):

Similar to your other posts....   sub in a = 4 and b = 2   (remember PEDMAS!)

3.14(a^2+ab) =

3.14( 4^2 + 4*2)

3.14 (16 + 8)

3.14 (24) =...........

As ILP posted:.....  Just plug in for   x =3  and y = 4 to get:

7 x^2 y =  7 * (3^2) * 4  =   7 * 9 * 4 = 252
