Answer:
(1,27)
Step-by-step explanation:
Knowing the formula to find the vertex of a parabola as -b/2a=x
In the equation b=6 and a=-3
Thus, -(6)/2(-3)=1
Plug in 1 back to the equation
-3(1)^2+6(1)+24
= -3+6+24
=27
Answer:
(1, 27)
Step-by-step explanation:
What I did was graphed it, and looked for the highest or lowest point. That point will be the vertex.
