The function f(x) when x=x-4 is or
Step-by-step explanation:
Given function f is defined by
Now to find the function f(x-4):
Put x=x-4 in the above function we get
(using the formula
)
(adding the like terms)
Therefore or
The function f(x) when x=x-4 is or
Answer:
x = 1
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 12 when x = - 2, then
k = =
= - 6, thus
y = - 6x ← equation of variation
When y = - 6, then
- 6 = - 6x ( divide both sides by - 6 )
x = 1
