Question

6.
Let f(x) be a function whose domain is (-5, 7) and g(x) = |2x + 5|,then
(a) Domain of fog(x) is [-6, 1]
(b) If f(x) is one-one then gof is one-one
(c) fog must be many one
(d) None of the above​

Answer 1

Answer:

Step-by-step explanation:

Since g is a modulus function hence fog(x) can have same values at two different values of x, hence fog(x) is many to one.
