The third term of x3+2x2+x+1=0 is eliminated by putting x=y+h. The values of h are
Find the maximum and minimum values, if any, of the following functions given by
f(x)=|x+2|−1
g(x)=−|x+1|+3
h(x)=sin (2x)+5
f(x)=|sin 4x+3|
h(x)=x+1, x ϵ (−1,1)
(i) f(x) = |x + 2| − 1 (ii) g(x) = − |x + 1| + 3
(iii) h(x) = sin(2x) + 5 (iv) f(x) = |sin 4x + 3|
(v) h(x) = x + 1, x (−1, 1)
