Please see the table.
Work Step by Step
Total supply = Domestic Supply + Imported Supply
Total - Domestic = Imported
$-16x^2+150x+8945-(8x^2+80x+8443)$
$-16x^2+150x+8945-8x^2-80x-8443$
$-24x^2+70x+502$
$x=0$
$y=-24x^2+70x+502$
$y=-24*0^2+70*0+502$
$y=0+0+502$
$y=502$
$x=1$
$y=-24x^2+70x+502$
$y=-24*1^2+70*1+502$
$y=-24+70+502$
$y=548$
$x=2$
$y=-24x^2+70x+502$
$y=-24*2^2+70*2+502$
$y=-24*4+140+502$
$y=-96+642$
$y=546$
$x=3$
$y=-24x^2+70x+502$
$y=-24*3^2+70*3+502$
$y=-24*9+210+502$
$y=-216+712$
$y=496$
$x=4$
$y=-24x^2+70x+502$
$y=-24*4^2+70*4+502$
$y=-24*16+280+502$
$y=-384+782$
$y=398$
