Question: find the equation y101xa2 c c is not under the...
Find the equation y= -c ('c' is not under the square root) that passes through the coordinates (-4,2), and the vertex of (0,5) where c>0
Find the effect of the change in the parameter 'a' in the above equation,
^find the effect in terms of vertex, dilation, and the amount of intersections with y^2 + x^2 = 25
Find the value 'a' such that the graph (with the same equation as above) has more than 1 point of intersection with y^2 + x^2 = 25 but no more than one intersection with y^2 + x^2 = 16
please show full working out and please make the answer as detailed as possible. i would really appreciate a response as soon as possible :)
