For f(x), when x=1, y=1, and when x=2, y=4. Since the graphs are both quadratic, you can assume f(x)=x².

For g(x), when x=2, y=1, and when x=4, y=4. So g(x)=(x²)÷4.

Now it's a given that g(x) is equivalent to f(k*x), so we can say

(x²)/4=(kx)²

4kx²=x²

k=1/4

The Walmart Batteries are 8.82/18 which is also 49 cents. So both batteries are the same price, you should buy the better quality battery in this situation.
