Question 821147: 1. This equation is given in vertex form, write it in standard form.
f(x)= -(3/4)(x+2)^2 +8
2. Convert each quadratic function to vertex form by completing the square.
a)y=x^2-9x+3
b)y= -2x^2+28x-7
3.Determine the vertex of the quadratic function.
y=-24x^2+18x+11
-state the axis of symmetry
-the miminum or maximum value
-the domain and range

That is a misunderstanding.
Vertex form IS standard form.
You could put #1 into GENERAL form through multiplying and simplifying.
#2,
Only a small amount of help to start with #b,
Factor the right hand side:
The missing square piece is ;
ADD and SUBTRACT 49 INSIDE the parenthesised quadratic expression, and simplify but adjusting the form into ;
Can you perform the necessary steps or do you still need help?
