Answer:
y = -4
Step-by-step explanation:
When y is directly proportional to x,
= y ∝ x
= y = kx
Finding k
the value of y = -2 when x = 4
-2 = k4
k = -2/4
k = -1/2
. What is the value of y when x = 8
Finding y
y = kx
y = -1/2 × 8
y = -4
11,000,000 + 700,00 + 60,000 + 800 + 20 + 5
You mutiply the 50 by 2 to get 100 but would change the 41 and multiply that by two and get 82/100
The inverse function of the function f(x) will be f⁻¹(x) = 4x + 48. Then the correct option is D.
The complete question is attached below.
<h3>What is inverse of a function?</h3>
Suppose that the given function is
f: X → Y
Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is
f⁻¹: Y → X
It simply means, inverse of 'f' is an undo operator, that takes back the effect of 'f'
The function is given below.
f(x) = (1/4)x – 12
Then the inverse function of the function f(x) will be
(1/4)f⁻¹(x) - 12 = x
f⁻¹(x) = 4x + 48
Then the correct option is D.
