Answer:
Step-by-step explanation:
Given is a function
This function is a parabola with vertex at (2,0) and axis of symmetry is x=2
Hence for x<2 the curve would be reflection of x>2
To get inverse we must get one to one funciton only.
So restrict the domain of f(x) to
Then we have f(x) as one to one with domain x≥2 and range is R+
For this inverse domain is R+ and range is
Move the 12 over
-6x > 12
divide by -6, and you must flip the sign since you are dividing by a negative number
x< - 2
Answer:
1/11 = 0.09
Step-by-step explanation:
problem best done with a tree diagram. let's focus on the blue branch for child 1. the probability of child 1 getting a blue marble is 4/12. now since he's choosing randomly and we assuming that after giving it away, there is 12-1=11 marbles left, the second child will have the probability 3/11 of getting a yellow marble. multiple those probabilities
4/12 × 3/11
1/3 × 3/11
3/33
1/11
