The definition of an increasing function f is A function f i

The definition of an increasing function f is. A function f is said to be increasing iff(z)

Solution

a) as the function is increasing

f(x1) < f(x2 ) for x1 < x2

the maximum number of horizontal intercepts it can have is 1

as it will cut the x axis maximum 1 time

b) maximum number of vertical intercepts is also 1

since the increasing function will cut the y axis maximum at 1 point

c) the equal consecutive changes in values of x the corresponding changes in f(x) is positive assuming change in x is positive

d) assuming change in x is positive , so for equal consecutive change in x corresponding values of f(x) are increasing
