How do you find the vertex of
y= -2x²–20x–51​

(-5,-1)

hope this helps :) plz brainliest

Step-by-step explanation:

you answer is a

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.
