So you need to put both the equation in the y equals if you have a graphing calculator
Then you compare the two equation
f(x) is an decay and g(x) is growth
For choice one and three, the answer choice doesn't make sense leaving you with two and four as the only ones.
Since f(x) is a decay, it cant be choice four either leaving choice 2 as the final answer
This makes sense because g(x) is a growth
I hope this helps!

Answer:
option: D is correct. ( (D) a markup of 15% on selling price is equivalent to a 85% markup on cost ).
Step-by-step explanation:
" Markup is the percentage difference between a product's cost and its selling price "
Since we are asked to Convert a markup of 15% on selling price to its equivalent markup on cost.
As there is a markup of 15% on selling price. Hence the cost of the product would be (100-15)%=85% of the selling price.
<em>Hence, a markup of 15% on selling price is equivalent to a 85% markup on cost.</em>
<em>Hence, option D is true.</em>
