Answer:
g(x) = (x + 3)^2
Step-by-step explanation:
When a function is shifted to the left or right we can think of a change of units, like a new independent variable is used.
If we have a quadratic function
and the graph is shifted 3 units to the left, then we can think of a new unit u that is:
The vertix of this parabola, that happens for u=0, happens for x=-3, as the graph is shifted 3 units to the left.
Then, the relation between u and x is:
We can use this relation in the new graph and replace u as:
Answer:
C. (-2, 1)
Step-by-step explanation:
See the attached graph.
The slope of the first line is -1, and its y-intercept is -1.
The slope of the second line is +1 and its y-intercept is +3.
The solution is the point that is common to both lines, (-2, 1).
