Question

assume the point (10,20) belongs to the graph of f of x what point belongs to the graph of y equals f x + 5

Answer 1

we have the point (10,20) -----> f(x)

y=f(x)+5

we have the following transformation

(x,y) ------> (x,y+5)

so

(10,20) ------> (10, 25)

therefore

the answer is

(10, 25)

Part 2

we have that

g(2)=0 ------> looking the table

g(g(2))=g(0)=2

therefore

the answer is 2g
