Question

The parent function f(x)=3sqrt(x-1) is transformed to g(x)=3sqrt(-x-1)Which graph correctly shows the functions f(x) and g(x)?

Answer 1

Answer: It should be B on plato

Explanation:

I graphed it

Answer 2

The graph is shown in the attached image

We know that:

Reflection across the y-axis gives us:

(x,y) ..................> (-x , y)

From the graph, we can note that each point on the f (x) function has a negative image on the g (x) function

For example:

point (2,3) in f (x) is (-2,3) in the g (x)

Therefore, we can deduce that g (x) is formed by reflecting f (x) across the y-axis

Hope this helps :)
