Hello :
y= -x²-4x-1
y = - (x²+4x+1)
y = - ((x²+4x+4)-4+1)
y = - ((x+2)²-3)
y = -(x+2)²+3 the vertex is A(-2 ; 3)
Find the inverse of that function:
y = e^x
Let's use a simple way. SPOE, APOE, DPOE, MPOE.
First, isolate the variable.
x5 + 3 = 2
-3 -3
x5 = -1/5 (5 divided by -1)
Answer to 5 divided by -1: -5.
A is the answer. (I'm pretty sure.)
