Simplify 3−2y+(−8y)+8.4

Which statements are true of the graph of h(x) = ^3 square root of x-4 ? check all that apply. the domain of h(x) is the set of all real numbers. the range of h(x) is the set of all real numbers. for all points (x, h( h(x) exists if and only if x – 4 0. the graph of h(x) is a translation of f(x) down 4 units. the graph of h(x) intercepts the x-axis at (4, 0).

How do i do this? i don’t understand

Daniel expanded the expression as shown below -2(-8x-4y+3/4)=-10x-8y-11/4 what errors did he make? check all that apply
