Question

Find the vertex , the line od symmetry, the max or min value of the equation function and graph the function.
f(x)-2x^2+2x+9
the x- coordenate of the vertex is ?
the y coordinate of the vertex is?
the equation of the line of symmetry is?
the max/min of f(x)is?
the value f(1/2)=19/2 is the max or min?
what would it look like as a grapht?

Answer 1

line of symmetry = -b/2a that is going to be our x value also

vertex (-b/2a, f(-b/2a))

so find these two and then we can move on

Answer 2

i got 1/2 , 19/2
