Naomi is deciding between two different movie streaming sites to subscribe to. Plan A costs $14 per month plus $1 per movie watched. Plan B costs $10 per month plus $2 per movie watched. Let AA represent the monthly cost of Plan A if Naomi watches xx per month, and let BB represent the monthly cost of Plan B if Naomi watches xx movies per month. Graph each function and determine which plan would be cheaper if Naomi plans on watching 6 movies each month.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
