That's not enough information to calculate your grade from.
-- You've told us the scores you have in things that go together
to make up (35 + 5 + 25) = 65% of your grade.
-- We don't know your scores in the things that make up the other
35% of your grade.
Answer:
Step-by-step explanation:
y=2(x-8)(x+2)
The x intercepts occur when y=0, so when x=8 and -2
The vertex is where the equation is at a minimum/maximum in this case (x,y)=(3,-50)
The axis of symmetry occurs between the two roots, 8 and -2 which x=3
The y intercept is the value of y when x=0, in this case (0, -32)
