1. Jovi and Amillia are playing a game using the spinner below. Jovi will win the game on his next spin if the arrow lands on a section labelled 6, 7, or 8. Jovi claims it is likely, but not certain, that he will win the game on the next spin. Explain why Jovi’s claim in correct or incorrect.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
