Question

Please please help me with this

Answer 1

B. y= f(x - 4).

Explanation:

The red graph is 4 units to the right of the blue one.

So x is replaced by x - 4.

Answer 2

B

Explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then shift to the right of a units

Here the red graph is the graph of f(x) moved 4 units to the right, thus

red graph has equation

y = f(x - 4) → B
