Hi there! The answer is g(x) = 4^x.
The function g(x) is an exponential function, and these functions grow faster than linear or quadratic formulas.
Answer:

Step-by-step explanation:
Given


Required
f(10)
An exponential function is represented as:

impleies that:
--- (1)
implies that
--- (2)
Divide (2) by (1)



Take 4th root

Substitute
in 


Solve for (a)


f(10) is calculated as:



You would cross multiply 53 times 5 and divide by 1
8/12 is still owed, and when you simplify the fraction it becomes 2/3
Answer: the large jar is cheaper
Step-by-step explanation:
If you divide the £1.54 by 440g and £1.26 by 340g, you'll find which one is cheaper per gram :
1.54/440 = 0.0035
1.26/340 = 0.0037
So, by comparing both prices/gram, you've found that the large jar is cheaper.
