Given information:
The given function is f(x)=x2.
Concept Used:
If a is positve real number, then the graph of f(xa) is the graph of y=f(x) shifted to the right a units.
If a>1, the graph of y=cf(x) is the graph of y=f(x) stretched vertically by a.
If a is positve real number, then the graph of f(x)a is the graph of y=f(x) shifted downward a units.
Calculation:
First, we have to shift the graph to the right by 7 units.
f(x7)=(x7)2
Now, stretched the graph by a factor of 9 units.
9f(x7)=9(x7)2
Now, shift the above graph downward by 3 units.
9f(x7)3=9(x7)23
Compare the new equation with the equation y=a(xh)2+k, we get
h=7 and k=3
Final Statement:
The new coordinates of the vertex for the new parabola function is (7,-3)
The new function is
g(x)=9(x7023)
