1) If the graph of “y=f(x)” is translated “a” units horizontally and “b” units vertically, then the equation of the translated graph is “y-b=f(x-a).”
“y-0=(x-2)^2+3(x-2)+4”
“y=x^2-4x+4+3x-6+4”
“y=x^2-x+2”
2) We start with the graph of “y=f(x).” The graph of “g(x)=f(-x)” is the graph of “y=f(x)” reflected in the “y” -axis . How points in graph of “f(x)” become points of new graph “g(x)” ?
“(a,b)to(-a,b)”
Visual effect: flip over the “y” -axis
The graph of “h(x)=3g(x)=3f(-x)” is the graph of “y=g(x)” stretched vertically by “3” units.
How points in graph of “g(x)” become points of new graph “h(x)”?
“(-a,b)to(-a,3b)”
Visual effect: stretch vertically by “3.”
How points in graph of “y=f(x)” become points of new graph “y=3f(-x)”?
“(a,b)to(-a,3b)”
