Explanation Given information: The equation, ln ( x − 1 ) + ln ( x + 1 ) = 2 ln 12 Concept used: The equivalent exponential form of a logarithm for a > 0 , x > 0 , a ≠ 1 is given by log b x = y if and only if x = b y Exponent property of Equality : If the same bases raised to different exponents are equal to each other, then their exponents will be equal as well. That is, if a m = a n then m = n Exponent property, 1 a n = a − n Product property of logarithm: log b m + log b n = log b ( m ⋅ n ) Power property of logarithm: n log b a = log b a n Calculation: To solve the given logarithmic equa

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
