    Three Algebra 1 students are comparing how fast their social media posts have spread. Their results are shown in the following table. Description Amber shared her photo with 3 people. They continued to share it, so the number of shares increases every day as shown by the function. Ben shared his post with 2 friends. Each of those friends shares with 3 more every day, so the number of shares triples every day. Carter shared his post with 10 friends, who each share with only 2 people each day. Social Media Post Shares f(x) = 3(4)x Day Number of Shares 0 2 1 6 2 18 Carter shared his post with 10 friends, who each share with only 2 people each day.

    3.Graph each function using at least 3 points for each line. All graphs should be placed together on the same coordinate plane, so be sure to label each line

    it is hard to read the post. what are the 3 equations for A , B and C ? (I'm using their first initial, easier to type)

    you don't mean B is f(x)= 2*3*x = 6x ? I assume you mean \[ f(x) = 2 \cdot 3^x \] ?

    its not an exponential function, my teacher would have told me to correct that if it was.

    to plot we need points pick x=0, 1,2 and find f(x) if we have f(x)= 6x what is f(0) ? f(1) ? f(2) ?

    ok. But first, ***Ben shared his post with 2 friends. Each of those friends shares with 3 more every day, so the number of shares triples every day. *** that says the first day 2 people have his post the next , 2*3 = 6 the next, 6*3 = 18 if we make that into an equation , it is \[ f(x) = 2 \cdot 3^x\] and we start at x=0 I am saying that equation for B must be exponential

    let's do the first equation f(x)=3*(4)^x for x=0, 1, 2 when x is 0 you have 3* 4^0 4^0 is 1 (anything to the zero power is 1) so we have 3*1 = 3 and one point is (0,3) can you find the "y value" when x is 1 ?

    you have 3*(4)^x erase the x and write in 1 in its place 3*(4)^1 now do order of operations: exponents first. what is 4^1 ?

    yes 3*3 is 9 but the formula for A is 3*4^x that is different from 3^x so far we found (0,3), (1,12), and now we want (2, ??) to find the number we erase the x and put in 2 in \[ 3 \cdot 4^x \] can you erase the x and write in 2 instead ?

    they want you to plot at least 3 points, so you have to find 3 points for each equation but assuming you show that work, it sounds ok to use a computer to plot the graphs. I use Geogebra (free download... but it takes a while) I know there are plotting tools on the web.
