A double ordinate of the parabola y^2=2ax is of length 4a . prove the lines joining the vertex to its ends are at right angles? ​

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

table 3 represents a direct variation function. : )
