A graph of y f(x) is given .No formula for fis given. Graph the given equation.
Solution
y = -2 f (x+1) -3
following transformation has been applied to the graph
1st----negative sign means reflection across x axis
2nd---2f(x) vertical stretch by 2 units , y values get doubled
3rd---- f(x+1)horizontal shift of 1 unit left
4th---- -3 means vertical shift of 3 units downwards
