Number of tangents drawn from the point (–1/2, 0) to the curve y = e {x} . (Here { } denotes fractional part function).
Text Solution
Verified by ExpertsThe correct answer is:
B
y = e {x} = e x–a in esa x ∈ [a, a + 1)
= e x–a = e {x}
equation of tangent
(Y – y) = 
(X – x)
passing through (–1/2, 0)
(0 – y) = e {x} (–1/2 – x)
⇒ –1 = 
⇒ x = 
∴ point fcUnq 
Number of tangent
