The stationary points of the curve x² +2y2 - 2x+8y-9= 0 are (1,-5) and (1,1). find the
nature of these points using second derivative test.
(8 marks

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
