Question

Transform the solid black function to match the dotted line please help explain and solve

Answer 1

we have that

the vertex of the parent function is the origin (0,0)

the vertex of the dotted graph is the point ( -1,3)

there is a translation of one unit to the left and 3 units up

the rule is

(x,y) -----> (x-1, y+3)

therefore

f(x+1)+3
