Fx loga x where a 1 the yintercept is SolutionDear Student

F(x) = log_a x, where a > 1, the y-intercept is: ?

Solution

Dear Student

Thank you for using CHegg !!

Given a curve f(x) = log _a (x)

Now clearly when x = 1 , f(x) = 0

When x = a, f(x) = 1

Y Intercept is defined as the point when the curve crosses y axis i.e. when x = 0 but given curve is not defined when x= 0

Hence the curve can touch y axis at f(x) = - Infinity.

Y Intercept = - Infinity
