y = 1/2x + 3
change x and y
x = 1/2y + 3
now find the value of y and that is inverse function
x - 3 =1/2 y
y = 2x- 6
f-(x) = 2x - 6
<u />
for both domain : ( - ∞ , + ∞ )
range f (x) : ( - ∞ , + ∞ ) - { 0 }
range f-(x) :( -∞ , +∞)
Answer:
(-2, 0)
Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
9 - 3 = (x/5)
6 = x/5
(x/5) = 6
x = 5x6
x = 30
Check
(30/5) + 3 = 9
6 + 3 = 9
