    that graph has a peak at y=1 (the highest it goes)

    function 2 is \[ f(x) = −x^2 + 2x − 3 \] match this with \[ a x^2 + bx+c\] to see a=-1 and b=2 then figure out x= -b/(2a) it has a peak at x= -2/(-2) = 1

    we want to find the y value of the peak for function 2 we know that happens at x= 1 (see the above post) put 1 in place of x in -x^2 + 2x -3 to get - (1*1) + 2*1 - 3 or -1 + 2 -3 1-3 -2 the peak is at y=-2

    which is higher (bigger) y= 1 for function 1 or y= -2 for function 2 ?
