The shipping cost for an on-line company increases exponential based on the number of dollars the consumer has spent. It can be represented by the equation y = 0.003(2)x where x represents every $10 spent. Shipping charges will max out at $20. The company has decided that they need to add a base shipping charge of $5. What will this new function be?
A) f(x) = 0.003(2)^x + 5
B) f(x) = 0.003(2)^x - 5 <<My answer
C) f(x) = 0.003(2)^x + 5
D) f(x) = 0.003(2)^x - 5
The answer is A
it is a
Hmmm. What does
they need to add a base shipping charge of $5
mean to you?
To find the new function after adding a base shipping charge of $5, we need to add this base charge to the existing exponential function.
The original function is y = 0.003(2)^x, where x represents every $10 spent.
To add the base shipping charge of $5, we simply add it to the function:
New function = 0.003(2)^x + 5.
Comparing the options, we can see that the correct answer is:
A) f(x) = 0.003(2)^x + 5.
