F(x) = g(x) when the values in the two table columns are equal. That is the case for x=0 and x=1, the two correct choices from your answer list.
The statement at the top says that the triangles are 'similar'. That means that the corresponding angles are equal, and each pair of corresponding sides have the same ratio. From the 4 and the 8, you can see that each side in the small one is 1/2 the length of the corresponding side in the big one. So the missing sides are 1/2 the length of the 7 and the 12.
The given functions appear to be ...

Of these, the exponential function g(x) will eventually exceed all others. That is the price of product 2, so ...
... The price of Product 2 will eventually exceed all others.
Answer:
y=0
Step-by-step explanation:
So your m=-2 or -2/1. And you say that your y-intercept is the origin. The origin is the (0,0). Therefore your y intercept is 0.
