<PRE><B>Question 981324</B>
Regarding the 2nd part where the drone crosses the parabola at two points
Choose two points on the parabola. for example
x1=-5; y1=11
x2=3; y2=27
:
Find a linear equation using these to points. Find the slope, then the intercept
From this I got y = 2x + 21
Looks like this
{{{ graph( 300, 200, -10, 10, -10, 50, -x^2+36, 2x+21) }}}
You can make a table from the linear equation and see that the points of intersection are included
