Each unit of brand awareness of a product generated by an ad campaign costs $.10 more than the previous one (i. e., the first costs .1, the second costs .1 more than that (.2), the third costs .1 more than that, (.3), and the overhead cost of $50 is needed to begin the ad campaign. each unit of awareness generates exactly $5 in revenue.
find a function that models this in terms of awareness and profit. profit will be a function of the accumulated awareness. graph it.
how much awareness gets us to break even?
how much maximizes the profit?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6
