if the vertex of f(x) is (0,3), what is the value for 3 x f(x-2)

Question

I need help with this question

Answer 1

3f(x - 2) indicates that the given point shifts horizontally 2 units to the right from its current position.  Then the y-coordinate is multiplied by 3.

 

The shift gives the point (2, 3).  Now multiply the y-coordinate of 3.  The final point is (2, 9).
