Appears that you've overlooked the need to share the possible answer choices.
f(x)=x^2x-1 has a parabolic graph with vertex at (0,-1). This is also the location of the vertex. Because the coefficient of x^2 is positive, this graph opens up. Thus, the smallest possible y value here is -1. The range of this function is
[-1, infinity).
You have to remember that "percent" means "hundredths".
So '25%' means 0.25 .
50 percent means 0.50 .
77% means 0.77 .
etc.
To find 41% of a number, multiply the number by 0.41 .
John gets 12, Walt, Matt, and Richie get 4 each
