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.

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
