Answer:
f(x) = 4^x
Step-by-step explanation:
In f(x) = (1/4)^x, 1/4 is equal to 0.25, which is less than 1, so its decreasing
In f(x) = 4^x, 4 is greater than 1, so its increasing
In f(x) = (0.4)^x, 0.4 is less than 1, so its decreasing
This is why f(x) = 4^x is the correct answer

Answer: 
Step-by-step explanation:
Given
The scale factor of two similar hexagons is 5:12.
The smaller hexagon has an area of 24 square units
we know, the ratio of two similar figures is equal to the square of the scale factor.
Suppose the area of the larger hexagon is A
![\therefore \dfrac{24}{A}=\left[\dfrac{5}{12}\right]^2\\\\\Rightarrow A=\left[\dfrac{12}{5}\right]^2\times 24\\\\\Rightarrow A=138.24\ \text{square units}](https://tex.z-dn.net/?f=%5Ctherefore%20%5Cdfrac%7B24%7D%7BA%7D%3D%5Cleft%5B%5Cdfrac%7B5%7D%7B12%7D%5Cright%5D%5E2%5C%5C%5C%5C%5CRightarrow%20A%3D%5Cleft%5B%5Cdfrac%7B12%7D%7B5%7D%5Cright%5D%5E2%5Ctimes%2024%5C%5C%5C%5C%5CRightarrow%20A%3D138.24%5C%20%5Ctext%7Bsquare%20units%7D)
