Answer:
<h2><em><u>2)</u></em><em><u> </u></em><em><u>two</u></em></h2>
Step-by-step explanation:
A line segment forms when it has two end points
The x-intercept is 12 and the y-intercept is -2
Standard form of an exponential function is y=ab^x
when x=0, y=3, 3=ab^0, so you can figure out that a=3
when x=-1, y=6, 6=3b^(-1), b^(-1)=2, b=1/2
so the equation is y=3(1/2)^x
