Let f(x)=logb(3×2). For what value of b is f(1)=3?
To evaluate: The value of
1. Chain rule:
For finding value of b, we have to use condition . So, we have to first find out the value of the derivative of f. Here, f is composition of functions, so to differentiate f we have to apply chain rule. For applying the chain rule, let . Then, .
