Question

If the point (-6, 10) lies on the graph of y=f(x) then which of the following points must lie on the graph of y=1/2f(x)?

Answer 1

(-6,5)

Explanation:

we have

y=f(x) ----> the parent function

y=1/2f(x) ---> the new y-value will be 1/2 times the original value

The rule of the transformation of f(x) to 1/2f(x) is

(x,y) -----> (x,y/2)

substitute the given value

(-6,10) ------> (-6,10/2)

(-6,10) ------> (-6,5)
