LOOK AT THE PICTURE PLEASE HELP ME IM STUCK AND NO ONE IS HELPING

The profit P, in dollars, of selling x widgets and y gadgets is given by the
function P(x, y) = 7x + 8y. Which corner point of the shaded region will
maximize the profit?

(if f(x)=4x^2 and g(x)=x+1, find (f o g)(x)

If you apply the changes below to the absolute value parent function, f(x)=\x\, which of these is the equation of the new function? shift 2 units to the left shift 3 units down a. g(x)=\x-3\-2 b. g(x)= \x-2\-3 c. g(x)= \x+3\-2 d. g(x)= \x+2\-3

How is working backward similar to solving an equation?
