An equation represents exponential growth if the base of the exponent is greater than 1.
Let's analyze the given options:
- \( f(x) = 4(0.07)^x \) - (0.07 is less than 1, represents exponential decay)
- \( f(x) = 2(0.44)^x \) - (0.44 is less than 1, represents exponential decay)
- \( f(x) = 12(6)^x \) - (6 is greater than 1, represents exponential growth)
- \( f(x) = 7(12)^x \) - (12 is greater than 1, represents exponential growth)
The equations that represent exponential growth are:
- \( f(x) = 12(6)^x \)
- \( f(x) = 7(12)^x \)
So, any of these two equations does represent exponential growth. If you need only one response, you can choose \( f(x) = 12(6)^x \) as it is listed first.
