Please revisit each of the threads you just created, and show what you've tried for each problem. We are here to help you, not do your work for you. In the future, please post 1 problem per thread because a thread with several problems posted can become convoluted and hard to follow with people trying to simultaneously help with all.

For 106 and 107 we need a value for x in order to find the value of f(x)
Hint for 79:
3x^2 = 11 - 14
3x^2 = -3
Square root of a negative number!
Hint complex numbers ....
