Question 991107:
1.Solve
x^2+3x−4/2x^2+−3≤ 0, indicating your answer by interval notation.
2.Solve: log2 [log3 (2x+1)]=2 (Q2 p.s: log2and log3 2and3 are in small letter)
3.−4X^2 + |x| = −3
4.Simplify |cos x − 1|
5.Given that f(x) =1/1+log10x and g(x) =1/x^2
(iii) Find (f ∘ g)(x) and state its domain and range.
(a) Domain: (−∞, 0)⋃(0, ∞) Range: (−∞, ∞)
(b) Domain: (−∞, 0)⋃(0, ∞) Range: (−∞, 0)⋃(0, ∞)
(c) Domain: (−∞, −√10)⋃(−√10, 0)⋃(0,√10)⋃(√10, ∞)
Range: (−∞, ∞)
(d) Domain: (−∞, −√10)⋃(−√10, 0)⋃(0,√10)⋃(√10, ∞)
Range: (−∞, 0)⋃(0, ∞)
thanks so much
