Hey there!
To find the value of f(-2), first locate a point on your graph with -2 as its x value. To do this, locate -2 on the x axis and move towards the function. When you do, you should find the point (-2, 4).
Therefore, your answer would be the y-value of the point, 4.
To find the value of f(5), you would do the same as above. When you locate your point, you should find (5,3).
Therefore, your answer would be the y-value of the point, 3.
Hope this helps! :)

Answer:
The correct option is;
0.28
Step-by-step explanation:
The given parameters are;
The mean score for Michael, = 150
The standard deviation, σ₁ = 30
The mean score for Alan, = 165
The standard deviation, σ₂ = 15
Taking n₁ = n₂ = 1
Taking μ₁ - μ₂ = 0
The p-value for a z-score of -0.577 from the z-table is 0.28434
Therefore, the probability that Michael, with mean score, = 150 will have a greater score than Alan, with a mean score of = 165 is 0.28434 ≈ 0.28
Therefore, the correct option is 0.28
Answer:
Step-by-step explanation:
<u>Nancy's balance:</u>
- 750*(1 + 0.06)^30 = $4308 <em>rounded to whole number</em>
<u>Alex's balance:</u>
- 1500*(1 + 0.06)^15 = $3595 <em>rounded to whole number</em>
<u>Options:</u>
A. Nancy's balance would be greater than Alex's in the end.
B. Nancy's balance is $4,308 and Alex's balance is $3,595.
C. Alex's balance would be greater than Nancy's in the end.
D. The investment and balance would be the same in the end.
