what transformations change the graph of f(x) to the graph of g(x)? f(x)=x^2 g(x)=(x+3)^2-7

f(x) = x²  to g(x) = (x + 3)² - 7

Notice the difference:
from 'x' to 'x + 3'
and then from 'x²' to '(x+3)² - 7'

The transformation that changes 'x' to 'x + 3' is the translation across the x-axis, three units to the left

The transformation that changes 'x²' to (x + 3)² - 7' is the translation across the y-axis, seven unit down

Refer to the graph attached below to visualize the transformation. Take the vertex of f(x) = x² and translate it three unit left and seven unit down to get g(x).
