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

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)

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
