f(x) = { [(e^x) - 1] / x ; if x not equal 0
... .{ b ......; if x = 0
What value of b makes f continuous at x = 0?
so.. the left side and right side must be equal in order to make
f continuous at x = 0
[(e^x) - 1] / x = b
[(e^x) - 1] = (b)(x)
e^x = (b)(x) + 1
.
.
.
dont know how to proceed..
should i introduce ln?
