Question nm 43. How do i go about calculating the answer.
Explanation / Answer
Note:
g(x) = C* f(x)
(i) stretches vertically by C units, if C>1
(ii) compresses vertically by C units, if 0<C<1.
Now,
g(x) = log (x4) = 4 log x = 4 f(x) (Because log am = m log a).
Here 4>1.
So by the above note, g can be obtained by vertically stretching f by a factor of 4.
