I’m stuck on these could you guys !

volume is 576in^3, surface is 342in^2

Step-by-step explanation:

volume with or without top is the same: 12·8·6=576

surface: 2·(12·8)+2·(12·6)+2·(8·6)=

=192+144+96=342

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
