Answer:
the probability of drawing a blue ball from bag A is 1/5 and the probability of drawing a red ball from bag B is 2/3.
Answer:
Step-by-step explanation:
<u>1)</u>
f(x) = -6x + 3
To get the inverse of this, make x be the subject of the formula.
let f(x) = y
6x = 3 - y
x = (3 - y)/6
∴ f(x) = (3 - x)/6
Truly f and g are inverse functions.
<u>2)</u>
f(x) = -3x²+ 5
let f(x) = y
y = -3x² + 5
3x² = 5 - y
x² = (5 - y)/3
x = √[(5 - y)/3]
f(x) = √[(5 - x)/3]
Truly f and g are inverse function.
