Suppose f(x)=x3. find the graph of f(x)-1

The midpoints of the sides of the large square are joined to form a smaller square. what is the area of the smaller square

Yo need asap pls ! markin da brainiest too !

Taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor with some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)= 2x+1 g(x)= 2x^2+1
