Question

write an equation, g(x), for the transformations of the parent function, f(x) =x , when it has a vertical stretch across the y-axis and moves up 1 units

Answer 1

Answer:

$g(x)=2x+1$

Step-by-step explanation:

A vertical stretch would just multiply the x-value by a certain amount greater than one. So let's just choose some arbitrary value such as 2. From here the y-axis moves up 1 unit, so we add 1 to the function since the y-value is moving up 1

$g(x)=2x+1$
