Having a look at the graph, we will find that:
For speed: it is increasing along the x-axis
For height: it is increasing along the y-axis
This means that the function is linearly increasing.
Based on this, the correct choice would be:
D. As speed increases, height increases


Multiply complex numbers 5+6i and 5-6i in the same way as you multiply binomials.

By definition, i² is -1.

Do the multiplications.

Now cancel -30i & +30i

Now the equation becomes

when y = -11, 0 + y is equal to -11.
the question is asking us to add 0 to the given value of y. the given value of y is -11, so place -11 into 0 + y and you get 0 + -11. since you are adding zero, you are making no changes to the y value, so it stays at -11.
