You can put this solution on YOUR website! -7x^2-8x+2
Domain is all x.
Range is minus infinity, because as x gets large, -x^2 gets large negative
TO
the vertex, which is -b/2a= - (-8)/-14=-4/7 for x
square that 16/49
multiply by -7
-16/7
add -8(-4/7)=32/7
add 14/7
30/7 is the y-value and the greatest value of the function.
range is (-oo, 30/7)
