+546 76) y=-cubedrootx-2 +5 <---- +5 is outside the sqrt
78) y=-3sqrt4x-16 <----4x-16 is in the sqrt
82) sqrt8x-16=2sqrtx+2
+4473 76) y=-cubedrootx-2 +5
Domain: Notice that this function can take on any x value, so x can be all real numbers.
Range: The same goes for the y values, so y can be all real numbers as well.
78) y=-3sqrt4x-16
y = -3sqrt(4(x - 4)) -->
y = -3sqrt(4)sqrt(x - 4) -->
y = -3(2)sqrt(x - 4) -->
y = -6sqrt(x - 4).
82) sqrt8x-16=2sqrtx+2
x = 6.
+546 rewriting to make it easier to graph for #78
76 find the domain and range (SO SORRY I DIDNT TELL YOU)
and #82 solve by graphing
