**Re: Are my answers correct? Quadratic and logarithmic modeling**

I actually have a few more things that i'd like you to check for me please.

Answers:

**Appetizer: {0<=x<=10 y=7 x>10 y=2(x-10)+7 or y=2x-13**

**Quest: {0<=x<=40 y=40 x>40 y=1(x-40)+40 or y=x)**

**Voyager: {0<=x<=60 y=60 x>60 y=.5(x-60)+60 or y=.5x+30**

Question:

CURRENT PACKS:

develop equations that model the three current packs. including the domain for each equation.

find the intersection points of at least 3 different models.

appetizer : monthly access fee \$7, included gigabyte 10, cost per additional gigabyte \$2

quest: monthly access fee \$40, included gigabyte 40, cost per additional gigabyte \$1

voyager: monthly access fee \$60, included gigabyte 60, cost per additional gigabyte

\$0.50

Extra notes:

i dont exactly remember how to get the intersection points, i know its obviously when y crosses with x, but how would i graph this?
