Question

Given f(x)=log4(x+3) and g(x)=3 find the x value such that f(x)=g(x)

A.
3

B.
9

C.
61

D.
78

Answer 1

To find the value of x when f(x) = g(x), we equate the two terms. log4(x+3) is equivalent to log(x+3)/log 4. We equate this to 3, which gives us log(X+3)/log4=3. This gives us the value of x which is 61.
