Identify the vertex and 4 points you used show work

Y=-x^2+6x-8

Explain below

Step-by-step explanation:

Y= -x²+6x-8 = Y=-(x²-6x+9)+1 = - (x-3)² + 1    (y=(x-h)²+k    (h,k): vertex)

vertex: (3 , 1)

4 points: Roots (2,0) (4,0)  y intercept: (0 , -8)   Random: (1 , -3)

it is b)

hope this : )

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
