Question

Describe how to determine f(x) and g(x) when x=5

Answer 1

243 and 394

Explanation:

f(x) is the exponential as its values increase by 3 every hour, then

when x = 5

f(5 ) = 81 × 3 = 243

---------------------------

g(x) is linear as there is a common difference between consecutive values of + 3 , then

when x = 5

g(x) = 391 + 3 = 394
