Step-by-step explanation:

a door is rectangular in shape

area = length × breadth

8 × 4

32

The area of the door is 32 ft

D

Step-by-step explanation:

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

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

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

Here h(x) is f(x) shifted 4 units , that is a > 0 , then

h(x) = → D
