Hello,

f(x)=x-2
g(x)=x²-7x-9

f(g(x))=f(x²-7x-9)=x²-7x-9-2=x²-7x-11

f(g(-1))=(-1)²-7*(-1)-11=1+7-11=-3

Starting with the parent function f(x)=x2, Braylin adds a positive k to f(x) to form a new function, g(x) = f(x) + k. The result
Lena [83]
Shifted up
For example: if f(x) = x^2 + 4, the parent function has a vertex at (0,0), but the +4 shifts the graph up 4 units on the y-axis so the vertex would be (0,4)
