Find a equivalent function to f(x)=4(7)^2x
a. f(x)=28^2x
b. f(x)=4(49)^x
c. f(x)=196^x
d. f(x)=16^x(49)^x

Option: B is correct. ()

Step-by-step explanation:

We are asked to find which expression is equivalent to the mathematical expression:

We know that any expression of the kind could also be represented as

Hence on converting the given expression using the above representation we have:

Hence f(x) could also be written as:

Hence, option B is correct.

i believe the correct answer is b.

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
