1. Which relation is not a function? Explain. 1) {(1,5),(2,6),(3,6),(4,7)} 2) {(4.7).(2,1),(-3,6),(3,4)}
3) ((-1,6),(1,3),(2,5),(1,7)} 4){(-1,2),(0,5),(5,0),(2,-1)}
7 Which function is not one-to-one? Fynlain

Suppose that f(0) = −3 and f '(x) ≤ 8 for all values of x. how large can f(4) possibly be? solution we are given that f is differentiable (and therefore continuous) everywhere. in particular, we can apply the mean value theorem on the interval [0, 4] . there exists a number c such that

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

If 3x+8=3x+8 is it one solution or no solution
