Match the following List – I with List – II

Answer and explanation

Correct answer A

The correct matching is (i) – (d), (ii) – (a), (iii) – (b) and (iv) – (c). A function satisfying f(−X)=f(X) f(-X) = f(X) is symmetric about the vertical axis and is defined as an even function (d), whereas a function satisfying f(−X)=−f(X) f(-X) = -f(X) is symmetric about the origin and is defined as an odd function (a). An equation of the form Y=X5 Y = X^5 , where a variable base is raised to a fixed real exponent, is a power function (b), while Y=5X Y = 5^X , where a constant base is raised to a variable exponent, is an exponential function (c).
