Question

If f(x) = x2, which of the following describes the graph of f(x) - 5?
A)The graph of f(x) - 5 is a vertical shift of f(x) = x2 five units up.
B)The graph of f(x) - 5 is a vertical shift of f(x) = x2 five units down.
C)The graph of f(x) - 5 is a horizontal shift of f(x) = x2 five units to the right.
D)The graph of f(x) - 5 is a horizontal shift of f(x) = x2 five units to the left.

Answer 1

you will subtract five from each output

Answer 2

what does subtracting five do to the graph?
hint: is does not go up

Answer 3

it goes down so it would be b
