    Could someone PLEASE double check this for me

    Would someone mind looking over this homework I have on functions? My teacher has a nasty habit of not bothering to teach us how to solve the questions she asks on the homework. I've done my best with what I could learn from google and the textbook. Thanks in advance, you guys are awesome.

    You might make a common denominator on 1c, but that just depends on how picky your instructor is?

    3c ... there are two times that v(t) = 0

    5a ... domain is incorrect

    5c ... range is incorrect

    by 3c I assume you meant 3b, which I did overlook is 0 @ both 0s and 2s. Thanks! Again with 5a I overlooked the placement of X under the radical, I've corrected it to x is less than or equal to 6. And with 5c I don't know what I was thinking. I used the FMAX function on my calculator and my new answer is y is greater than or equal to zero but less than or equal to the square root of 5 over 10. Thanks for all your help! Truly awesome.
