Question

Find an equivalent function to f(x) = 4(7)2x.
f(x) = 282x
f(x) = 4(49)x
f(x) = 196x
f(x) = 16x(49)x

Answer 1

Solution:

The Given function is : f(x)= 4 (7)2 x= 56 x →None of the option Matches.

But it appears like the function should be like this : f(x)= 4.7²x

Two functions are said to be Equivalent if they are written in different ways ,but the end result is same.

So, f(x)= (4 × 7× 7) x

           =  196 x →→Option (C)
