Question

The parent function of a graph is f(x) = x2. The graph shifts a units to the left and down b units. Which function models the transformed function?

Answer 1

to shift a function c units to the left, add c to every x
to shift a function c units down, minus c from the whole function

so a units left and down b unit

$f(x)=(x+a)^2-b$ is the transformed function
