Question

HEEELLPPPPP!!!
Which of the following is the correct equation for this function?

Answer 1

Notice that the graph passes through the origin (0,0). The only choice that x = 0 and y = 0 works is choice (A).

Many other ways to solve the problem.

Answer 2

Well it starts (1,-2) which states your points

Answer 3

option a because you can see it is crossing through 2,0
put that in the first equation and hence you can get it

Answer 4

Thank you all so much :) so because it passes throug (2,0), it has to be a?
